There are two additional layers of symbols that the mac keyboard can type by holding down the Option key or Option + Shift key simultaneously. Here are the built-in symbols for the two layers:   However, I would never use most of the symbols such as , „, or ∏, and some of the symbols I frequently uses, such as σ, p̂, and x̅ are not included. Is there a way to customize the keyboard layer characters?

I recently moved to OS X and I find the system "Russian Phonetic" layout unsatisfying (it's not the one that I'm used to). How can I create a custom layout?  I've read about , but the layout I created and copied to Library/Keyboard Layouts doesn't show up in Keyboard Preferences.  I'm using OS X 10.9 Mavericks. I searched for solutions in internet, but most of them were outdated.

I asked  but I can't make that solutions work on Unity. I want to use the keys ´ followed by c and the output should be "ç". It works that way in Windows out of the box, and it did work in Ubuntu 10.10 following the solutions given in the question above. But in 11.04 it outputs "ć". How to change that?

I had an little issue when loggin in with Safari on Mac OS X (El Capitan).   When entering the password in Safari, there is a key symbol that lets you choose among any password that is stored in your keychain. This button interferes with the "forgot?" button that Stack Exchange adds and you can't press the Safari button.     Please move this "forgot?" button below the text field, like most other sites implement this.

I am confused about how Ctrl-key combinations work in terminal. In bash man page, there are various combinations such as:   C-e - go to end of the line C-f - go one character forward   etc.  But then there are some undocumented shortcuts such as:   C-j (OR C-m) for return key. C-h for backspace C-i for tab etc.   Are these shortcuts just forgotten to be documented? Or, because   C-j is LF C-m is CR C-i is Tab   in ASCII, is this somehow a "default" behavior? In other words, is the behavior for C-j, C-m and C-i not implemented by bash but by something else?  Another question is, when I press C-v and left arrow key, ^[[D appears on screen. I.e, ESC-[-d. But when I press ESC-[-d, the cursor does not move left. What is the reason for this?  EDIT:  Initially, I have thought that when I press C-j, the keyboard directly sends 00001010 to kernel. But then I decided that this is not the case, because using programs such as xev or evtest, I have observed that key presses to Control and j appear as different events. So when I press C-j, the keyboard does not send 00001010, but probably multiple bytes. Then where the conversion of these multiple bytes to 00001010 is done?

How can I derive the character sequence that represents a certain keystroke in screen? I mean, what bind takes as input. For instance, 's' represents the obvious keystroke on the 's' key. 'S' represents 'shift+s'. But the representation of other more complex combinations are unclear to me and the scheme that is followed seems quite obscure.  I have searched all around and , but I couldn't find the answer. So I guess the best is to try to understand the general scheme. I have also seen , but it's now working for me.  Can someone explain what scheme/rules screen follows for this? What are the rules to derive the representation of any arbitrary key combination? And are they screen specific, or shared with other software? Other GNU software maybe? Where is this documented?

I am used to the fact that LaTeX will only know letters like ä, ö, ü, or ß if I use packages like  \usepackage{ucs} \usepackage[utf8x]{inputenc} \usepackage[T1]{fontenc}   Today, I tried LaTeX on a Mac for the first time, using the MacTeX distribution and texmaker. Without writing down any packages, all umlauts and ß were accepted correctly from scratch. Why is that and will the usage of special letters without using the packages cause any problems?

I just bought a wired mac keyboard. Where I would expect numlock to be, it has a key with this mysterious symbol on:  ⌧ (a rectangular box with a cross through it)  What is this button?

Is there a way to create Barcodes (128 standard) on a Mac, preferably via an add-in?  I need it to create barcodes in Excel sheets (or moreso a friend of mine needs it).   I have tried all VBA macros and fonts I found on Google, but none give me a scannable result (usually there are weird characters like ó's mixed in). Does anybody have a working solution?

Now, my version of TeXworks is 0.4.5r.1280 and I can't have the " character on the keyboard.    I have ``  or '' instead. Why?  And It's the same with Alt+034. I'm very disappointed with that.

Using Macbook Air M1. The keyboard Fn (Function) key has a globe icon to switch between languages. It works but a bit quirky. When it's not working, it tries to switch language but couldn't, and when I switch screen, the language switching dialog keeps popping up. To make the keyboard Fn key work again in switching language, I have to restart my computer. See video attached - the Fn key is not even pressed.

Here is what the layout of an Italian keyboard looks like:  As you can see, the curly braces, which are absolutely necessary to write code in any of C, C++, JavaScript, Java, Objective-C, and others, appear in purple in this picture. This is because while the other characters can be seen visually as printed characters on most Italian keyboards, these purple characters are actually usually not printed on the keyboard's keys. These characters, found in the upper right corners of the given keys, can usually be generated with the following key combinations: (RIGHT SHIFT or LEFT SHIFT) + (RIGHT CTRL or LEFT CTRL) + (Alt or AltGR) + ([ or ]) (Actually as the MSKLC application shows, SHIFT + AltGr + [ and SHIFT + AltGr + ] are enough to generate the curly braces.) Characters such as the at (@) sign (called 'chiocciola' in Italian) and the hash (#) key (called 'cancelletto' in Italian) found in the lower right hand corner of the keyboard can be generated easily as follows (AltGr + @) or (AltGr + #). Such characters are also fundamental to programming as they can, for instance, be found in CSS, namely with media queries and with selectors referring to the id html attribute. Upon further inspection, we can see that all of the US ASCII keyboard / programmer's keyboard are covered by the keys of the Italian keyboard, except for the following, which are the tilde, which is especially useful on the Linux command line and is used to refer to a user's home directory on such system, as well as the back-tick (`), also known as the back-quote, which is also very useful on the Linux shell when we want to turn the output of a command into a command-line input. So, here comes the question: With all those empty upper-right hand corners of keys, why isn't there a better way of generating these characters, perhaps through a CTRL-ALT-SHIFT modifier key combination? All I've been able to find regarding generation of these characters are the following ALT-codes:  ALT code 96  corresponds to ` ALT code 123 corresponds to { ALT code 125 corresponds to } ALT code 126 corresponds to ~  and to generate a character via an ALT code, you make sure that the NumLock key on your keypad is toggled on, hold down the ALT key, enter the keycode, and release the ALT key. ALT code are documented at:  If someone knows of a better way of inserting these characters from an Italian keyboard without switching the keyboard layout in the Control Panel, then please let me know. Thanks.

I am curious as to whether there is an equivalent to the Alt-. command on Mac. On my computer it inserts the following character: ≥, instead of showing the .

So I've been using the MacBook Pro with Touch bar for a week and the Touch Bar seems pretty convenient. However, I haven't found an option to customize the Touch Bar for a specific app.  For example, whenever I code via , I'm used to having the F[0-12] Buttons (which aren't displayed in the keyboard anymore in favor of the Touch Bar). I know that if I'm holding the fn button, I'll be able to see the F[0-12] Buttons. But I want them to be displayed by default without the need to hold the fn button.  Is there a way I can achieve this?

What is the font that's used in Mac OS X's graphical user interface (GUI), in the menus, dialog boxes, etc.? Is it different from what was used in the classic Mac OS (i.e. OS 9 or older)? If so, what are the fonts back then? I like the font but never knew what it was. Thanks.

On a Mac, symbols are often used for keys rather than names. In Adobe Indesign for Mac, the keyboard shortcuts for inserting various break characters are described using what looks like an up arrow / caret / chevron pointing into a flat horizontal line:     It's the symbol on the right I'm asking about.  After much searching, I found it on the far bottom right of the full-size Apple keyboard. It's the... enter-like key (?) in the bottom right of the numeric keypad.    So two related questions:   What's it called? Is it possible to trigger this key (for use in keyboard shortcuts) when using a keyboard without a numeric keypad (like a wireless keyboard or laptop keyboard)? If so, how?

Is there any way of selecting a text with keyboard the way I do it normally using Shift+arrows.
