How to unfocus a file using keyboard on Windows?
Is there a keyboard shortcut to "unselect" in Windows Explorer?
How do people at Hogwarts usually tell the time? Why would I want to install a snap if I can install via apt instead? This is not a duplicate of the following questions     because:  My question specifically states that I am interested in end-user experience, not ease or efficiency of development, which is what the other question largely refers to.  As has been noted, development/deployment affects end-user experience, but it is not all there is to it, and neither of the referenced questions address issues that directly impact an end-user's ability to use the application (e.g. trouble accessing data on other partitions, sluggishness, etc.) Maybe &quot;compelling&quot; wasn't the right word to use; my intent was to ask about real-world, experiential consequences, i.e., things that happen or  don't happen, as opposed to theoretical/architectural statements that, while presumably accurate, don't appear to be backed up with any real-world examples to support the statement. I should have stated more directly that my intention was to get answers that consider the balance of &quot;advantages&quot; to snaps against the real-world downsides experienced by end-users. The &quot;duplicate&quot; question is largely theoretical, and doesn't discuss end-user experience at all. The &quot;duplicate&quot; question makes no mention of anything remotely similar to the example I used here, i.e., that there is an end-user downside to snaps (in this case, lack of access to data on other partitions and snap app performance) that isn't discussed in any available documentation that I can find.   While I understand that snap has a big advantage in making apps more widely available, is there any compelling reason to choose snap over apt, if the app is available for my distro/version via an apt package? I am curious because I've been doing some reading about snaps, and all the excitement about the method seems to be about things that are advantageous for app developers, but I've seen virtually nothing on how this makes life easier for end users (aside from the obvious; that they may be able to install apps that aren't otherwise available on their distro/version). I installed snapd and installed a couple of snaps and was really frustrated and disappointed.  The snap apps are slow and it's difficult, if not impossible, to access files on other partitions from within the snap. While I've seen plenty of info that says snaps are &quot;faster,&quot; &quot;easier,&quot; &quot;safer,&quot; etc., I haven't been able to find anything that explains why or how this is actually the case. Being very new to Linux, I am wondering if maybe I'm just missing something obvious? To be clear, I understand why the technology might be useful overall, but I can't find anything that explains whether/why it is a better option even when the app in question is available for install via a more traditional method, and all dependencies are met. Updating a chart dynamically in Numbers Background: I've been having some sleep issues so I have started tracking my sleep habits along with some other data but so far, they are just entries in Evernote and as such it is not possible to see any patterns. Obviously I need a spreadsheet app with charting capabilities (doh!). I've been using a great iPhone app called  for data collection for sleep times and then enter those into Evernote.  I have the iWork set so I have been looking at Numbers and going through some tutorials but I still can't tell if it will do what I want. Given that my data set will increase daily, I'd like to be able to "page through" a chart/data set, so it shows say the last 30 data entries. With all the tutorials I have seen, the charts are of fixed size and adding more data to a linked table just causes the chart to cram more stuff in.  Can Numbers do this sort of "paging" of data? I would like to have this sort of "on the fly" charting rather than having to explicitly build a chart each time I want to visualize the data.   (sorry the question is rather garbled: I don't know really anything about using a spreadsheet type app) Samsung galaxy S4 Blacked out Screen need to retreive files How to modify the page at admin/structure/types?

Add a "flag" button in the revision list Let $\times$ = cross product and $a$ and $b$ have vector signs on them.  $a = [a_1, a_2, a_3]$  $b = [b_1, b_2, b_3]$  How would I prove this? Do I expand out cross product?  Any help is appreciated! How to Disable new terms (free tagging) with Taxonomies? I have a "term reference" field, in a form that uses an auto-complete widget. I want to limit user input to terms in the vocabulary only, and output a message when a user tries to enter a non existing term.  I found the  module. However this does not work with forms that contain a field collection or a field group.  There is also a contributed patch . But I was wondering whether there was a simpler/cleaner solution like a module or maybe I missed an already existing way of doing it with latest drupal and taxonomy versions. Showing there is no ring whose additive group is isomorphic to $\mathbb{Q}/\mathbb{Z}$ Word for the opposite of "hypochondriasis" We let a>0 and b>0 and  we have $\sum_{n=0}^{\infty}b^n-a^n$. We have to find all values a,b>0 where $\sum_{n=0}^{\infty}b^n-a^n$ is convergent. I think I can use that $$\sum_{n=0}^{\infty} b_n &lt; \infty , \sum_{n=0}^{\infty} a_n &lt; \infty \implies \sum_{n=0}^{\infty} (b_n-a_n) &lt; \infty. $$. And I think $\sum_{n=0}^{\infty}b^n$ and $\sum_{n=0}^{\infty}a^n$ is convergent if a&lt;1 and b&lt;1? It will make sense. But how can I show it? Cost increase and suspend During a recent game, my opponent Suspended two  in the same turn. Then, during my turn, I played a .    The way we resolved it, is that at the next turn, my opponent payed 1 for the second Rift Bolt. I'm not sure if this is correct, because the rule text for supspend says that when you remove the last suspend counter you cast the spell without paying its mana cost.  So, to me, it sounds like even if the cost was increased, one still does not need to pay for it.    What's the correct thing to do? If actually one needs to pay for the second suspended spell, what would happen if he can't?
