Occasionally, I accidentally hit the cmd that removes the Opera Toolbar in Full Screen Mode. I always have difficulty finding a quick answer to resolve the issue, so I wanted to create a question and answer it for myself and others in the future.
Searching for a solution often leads to threads with answers that do not resolve the issue or lead to folks being confused, I hope this will be a quick reference to the solution.
To Show-Hide the Opera Toolbar in Full-Screen mode, press Shift + CMD + F. Alternatively, you may find the option in the View Tab of the Opera Application, the option is called "Hide Toolbar in Fullscreen Mode" or "Show Toolbar in Fullscreen Mode".

I am following along a tutorial for Flutter using Android Studio. The instructor's screen shows more detailed tooltips / hints than my environment does.
I am unsure of how to enable these extra details.
Examples
Instructor's Screen (extra tooltip details in red):
My Screen
Go to Preferences->Editor->General->Code Completion
Check the box "Show the documentation popup in xxx ms"
After having the Basic Code Completion open (Control + Space), then hit Control + Q (Win/Linux) or Control + J (Mac) to open the Quick Documentation Lookup, this will make your screen appear as your instructors. Alternatively, just hit the last keyboard shortcut to only see the Quick Documentation Lookup.

I somehow turned the documentation popup to be manually closed. It's incredibly annoying and I can't find the setting to undo it. Whatever I did adds maximize, minimize buttons and these windows have to be manually closed now.
I actually found out. It's called pinned mode. I got into it by clicking the pin icon on the window at the top right. Of course once you're in pinned mode, and you try to deselect it from the gear, nothing happens.
How to fix
enable toolbars
hit the red X to restore popup
Is there a way when documentation popup on AS to not hide immediately after it is showed by moving mouse on some class. What I mean. I move mouse cursor above Activity class and documentation is popup is showed, but when I try to move mouse above this popup (because I have to scroll it) it disappears. I can hold ctrl and then is will not hide, but if I press on it while holdint ctrl down it will disappear (so I should move cursor above it, release ctrl and after that to start scrolling). So is there an option to change this behaviour to be like in eclipse - documentation pop up is showed and if you move mouse above it you can scroll, otherwise it is closed.
There are a lot of bugs surrounding this UI element. I'm currently having the opposite problem where it won't go away unless I manually close it. I suspect in your case, a timeout is triggering too early, or some other event is erroneously hiding the window.
This workaround may be helpful. You can explicitly pop the documentation window from the View > Tool Windows > Documentation menu option. This will cause the tool window tab to appear on the right gutter by default. Right-clicking on the Documentation tab will pop up a menu that will allow you to pin the window, or dock it permanently in the UI by disabling "Floating Mode" and optionally moving it to the other side or the bottom.
Till last time when I used Android Studio a few hours ago, I had a sidebar of controls like 'Clear' and 'Terminate Application' etc. Like this side bar in the Run perspective.
I was using the control to easily terminate applications. But now it's gone, and I don't know how to terminate my applications.
So what should I do to get it back? Is there another easy way to terminate apps?
Addendum: I have seen this question, but I don't know how to find that DDMS perspective. And where are my controls from the Logcat gone?
Came here looking for answer but figure out one myself,in case anyone needs it anyway:
Right click the Android tab (where it says Android above the Emulator/Device name), when the menu pops select 'Show toolbar' .
Android Studio layout has changed since 2015, so for today (Android Studio 4.2.2):
The context menu popup of the Logcat tab (accessible through the little gear icon on the top right of the tab) has the option "show toolbar".
This will bring back toolbar on the left side of Logcat. Hope that info will help someone someday :)
This is the popup I mean:
It happens to obscure the indicator margin for a couple of lines, making it impossible to drag the current statement indicator to those lines.
The "Debugging" toolbar has a button called "Show threads in source":
Turn it off to disable this pop-up, along with the messy-looking graphic underneath the current statement indicator:
(took me far too long to find this, and Googling didn't help, hence this answer... it doesn't help that this button cannot be found by searching for "thread"in the otherwise excellent Quick Launch search box)
