macOS keyboard shortcuts are not like native for selecting text

[juliusknorr]

Describe the Bug

Keyboard shortcuts on mac os are not as used to from native apps

Steps to Reproduce

Use keyboard shortcuts in writer as described below

Expected Behavior

Command+Command+← selects everything to the left
Command+Command+→ selects everything to the right
Option+Command+← selects the word to the left
Option+Command+→ selects the word to the right

Actual Behavior

Command+Command+← selects the word to the left
Command+Command+→ selects the word to the right
Not sure which shortcuts trigger selecting everything to line start / line end

Does anyone have some pointers where those are handled? I'd be interested in contributing a fix there
