I configured general "Edit" shortcuts like Ctrl-C, Ctrl-V, Ctrl-A, Ctrl-X, etc. shortcuts in "Linux/Windows" style trough System preferences > Keyboard > Shortcuts > App shortcuts > All Applications like so:

I also swapped Mac's Fn -> Ctrl in "Modifier keys" and physical keys on keyboard. Running on Monterey 12.1 Macbook pro m1

In some applications like Notes, Pages, Terminal, Telegram, Intelij IDEA it works as expected. But in some apps like Slack, RDM, Chrome in some cases it works weird.

Most annoying is jumping to the end of the text-area after pressing Ctrl-V somewhere inside text while editing textarea. First press of Ctrl-V jumps to end of textarea, second press of Ctrl-V - paste text. Such behaviour repeats in Slack and Chrome textareas (in Chrome's address bar works fine).

Another annoying bug is sometimes Ctrl-A moves cursor to the start of line instead of "Select All". Mostly repeats also in textareas of different apps (Slack, Chrome, Postman).

Looks like Mac has it own shortcuts for Ctrl-V and Ctrl-A specifically for textareas... I want to learn how to find them and disable/reassign.
