Move cursor via WASD hotkeys

[ohCiep6j]

Is your feature request related to a problem? Please describe.

Using only the touch screen while editing text, I often can't move the cursor to the exact position I need it at.

Describe the solution you'd like

Press and hold one of the volume keys on the side of my android device to turn the WASD keys on the touch keyboard into arrow keys, allowing to move the cursor one character at a time. Similar to the way the Termux app works.

Describe alternatives you've considered

Gboard's "text edit" feature - not as convenient.
