Why is shorcuts in Anki so inconsistent between the main program and the browser?

Suspend a card is @ in main progarm, but Ctrl J in browser.

Ctrl+E is Export in main program, Ctrl+E is New Note in browser.

Just two examples of same shortcut is two different actions and the same action is two different shortcuts in Anki and the browser.

The shortcuts is so inconsistent and is all over the place.
