^{Originally posted by mwsmws22 October 17, 2025} I am trying to switch

shift + → (right ten columns) with → (right half a page). and shift + ← (left ten columns) with ← (left half a page).

Problem is, I can't figure out the keymap codes for these arrow keys. Can someone point me in the right direction?
