gedit broken shortcut keys, has mod2 - gedit

I have been trying to play around with gedit and came across the "shortcut editor" plugin. But somehow, it messed up my key bindings. It no longer works. Everytime I try to setup a new shortcut, I get a "Mod2" addition to the bind.
How do I reset to the default key bindings? How do I remove Mod2?
Thanks,
Wenbert
EDIT:
Google does not seem to return any relevant results regarding this issue.

I had the same problem but I solved it by toggling off the numlock

I'm going to answer my question. I have solved it after hours of trial and error.
I was connecting to my Linux machine running gedit using Synergy. So I jsut transfered the keyboard to the USB port running the linux machine and then reconfigured the Shortcut Editor Plugin for gedit.
The shortcuts are now properly set by the plugin.

VSCode Java Extension Pack: sudden linter, refactoring, semantic highlighting issues

Don't know how to go about describing the details of my problem, but out of nowhere all of the useful code tools that I use for Java have partially stopped working. Go To Definition, Change All Occurences, and hover functionalities have all disappeared. I'm working on a remote machine through SSH, but I don't think that's the problem because another computer I'm working on works fine.
I've tried uninstalling and reinstalling every extension I have, I've tried quitting and restarting VSCode, I've tried deleting and reinstalling the application, all to no avail. I'm desperately in need of help with this problem
Finally figured it out -- I had to start the RedHat language server extension from a clean slate with the command Java: Clean Java Language Server Workspace

Why are the dead keys not working on Intellij on Kubuntu 21.10?

On Kubuntu 21.10, the dead keys do not work on Intellij.
I have two keyboard set up: plain US english and US english with dead keys. Those do not work even when I select the correct keyboard layout using KDE settings editor.
Answering my question:
The settings seem to look for a fcitx package, even displaying an error like "fcitx not found on dbus". The package is fcitx5, the old version seems to be fcitx.
Installing the fcitx5 package then reloading Intellij solved the problem.
sudo apt install fcitx5
Then restart Intellij.

macOS use "Command key" as zsh shorcuts

I want to use macOS command key as iterm2's shortcut. (not an alias, I mean ^W ^E Command-B, etc)
Is this possible?
I search for this question and found some tips in zsh doc.
However, I still cannot fix my problem.
Besides, is there any best practice for writing zle config?
I totally messed up by lots of ways to change my custom terminal shortcuts.
Is there somebody can help?
a detail tutorial article will be great, too
If you're on macOS, rather than trying to configure keyboard shortcuts in every shell and/or terminal you use, it's much easier to just configure it once, on the OS level, with Karabiner-Elements. It even comes with a handy module for it, called Keyboard shortcuts for terminal apps, so you don't have to configure it yourself.

Ubuntu 18 Intellij Shortcut Conflict

Recently almost all my intellij shorctuts (defaults) stopped working. For example F9 which is a shortcut for "Resume program" currently shows all windows side by side. I've already tried solutions proposed in similar threads, I've looked into keyboard settings and did not found any conflicts there. I've also used dconf editor in order to make sure I did not miss anything - no luck there either. Any idea what may cause this?
I've figured it out - as it turned out my FN key was in always ON mode.

Keyboard locks Win10 IntelliJ

Using: Windows 10
IntelliJ version: 15(.0.3)
Problem:
I currently have issues that several keys suddenly are 'locked' or something. Keys a-z, 0-9 and some others. Keycombinations like CTRL+F... etc., DELETE, BACKSPACE keep working. The keys are locked everywhere in Windows. And the combinations can still be used everywhere.
When happens this:
This happens when I work in IntelliJ and it always happend when I double pressed a String for selecting it, but not the first time (random). So maybe this is a key setting in Windows or something.
Temporary solution:
Reboot. :(
I already saw the following post: Weird keyboard locks in IntelliJ IDEA (delete & arrow keys, etc.)
This is an older post and there is assumed that I need to uncheck the Vim Emulator. I don't have this plug-in.
Edit: Current solution
Re-installed IntelliJ.
I've encountered this exact same issue and the the removal of the VIM plugin (didn't have a VIM emulator) fixed it, under intellij 2016.2.4 on windows 10.
Open settings -> Plugins -> search for VIM -> remove
