Selecting lines of code in Pycharm is working strangely - copy

Recently, I wrote a block of code, and tried to copy and paste some functions around the code. But when highlighting the block of code I am trying to select, it exhibits strange behaviour. The first picture is the faulty case, and the second picture is the normal case.
First of all, I can click anywhere on my script even though I dont have spaces there.. if that makes sense (sorry I cant explain it any other way). Second, when I drag my mouse up, it drags up for only that section. Looking at the faulty screen shot, if I were to copy that block, it would only copy the parts in blue... Normally when I drag my mouse up, it automatically highlights the whole line as seen in the normal picture. Also, notice the giant white line on the faulty highlighting compared to the normal highlighting. I am wondering how I can go back to my old normal highlighting...

I think I was able to reproduce the problem by enabling column selection mode.
Try going to Edit-->Column Selection Mode. Uncheck it. If this was the problem, perhaps it was a finger flub which performed a shortkey operation.

How to see error when VS code yellow highlights a line?

I just started programming in flutter and I keep getting these types of errors with the yellow highlight over a line. The highlight goes away if I pressed the green restart button and as long as the issue is gone. The problem is that sometimes I will just retype the yellow-highlighted code in a different order and it begins to work again. So far I have been able to fix the issues, but it's really annoying because I have to constantly guess and check and retype, praying on my luck to fix it. Is there a way I could actually see the error message? I'm pretty sure it's minor, since I copy and pasted this straight from official documentation.
Edit: I realized that when I right click on the yellow arrow, it shows "run to line" and I can run the code without issues. However, the yellow arrow reappears from time to time, seemingly randomly.

How to stop prettier from random line breaks?

So Prettier is finicky as it is, but here's a weird situation. The image below shows what happens after a save in VS Code with Prettier set up normally. It randomly removed the tabs for these two lines. If I tab it back into place and save it does it again.
Can anyone tell me why, and how to stop it? Makes the code look really bad.

VS Code automatic indentation

I have a problem with automatic indentation in VS Code. If you pay attention to the gif below, you will see that the editor only moves a tab forward for the first time, but the second time it should automatically detect that a tab moves forward, but this is not the case. Many editors do not have this problem, but it has really become a problem for me. Also, for example, I do not want to press a shortcut key to solve this problem, I expect the editor to handle.
I found theanswer. Just disable trimAutoWhitespace in VS Code settings.

Smart Caret in Eclipse stops working for some files

I am using Eclipse and I am coding java. I really like the "Smart Caret" option for the Home and End buttons since it allows you to go the start and end of a line but not past any whitespaces. Also the Home key will take you to the start of a comment, rather than the start of the line. And you can cycle through different positions with these keys. And this is how the editor was by default, from installation.
However one thing that has happened a few times now is that when I am writing code in the editor, this functionality just vanishes. It is seemingly random when it happens and the weirdest part, I think, is that it is file specific. So all of a sudden when I am writing, the Home and End keys start taking me to the very start and end of the line I am on. It is as if I am accidentally pressing some hotkey to disable these Smart Carets for the specific file.
It does not help to disable and re-enable the Smart Caret option in Preferences. And beyond that I do not really know what to do. Is this a bug? It is incredibly annoying when it happens. Being used to things working one way, then having them spontaneously change and then again having them back to the default when I am editing a different file.

Keyboard input blocks in VSCode

Since yesterday, I have a problem when want to edit code in VSCode. Apparently, after changing focus within VSCode, say switching to the menu bar or a to different view and then coming back to the editor view, the cursor changed from the caret to a filled rectangle, and normal keyboard input is blocked. I need to do something like pressing the Escape key which on the first, second, or third try finally puts me into overwrite mode from which I have to switch to insert mode. This is a very annoying situation. Does anyone have a remedy for this?
Apparently, I happened somehow to switch to the vim schema. Once I became aware of this, I simply switched back to the VS schema which I'm used to, and everything works as desired.
