Don't allow gj type mappings
Don't allow gj type mappings

Assuming a small screen and 'wrap' set:

The cursor is forced to stay in a certain column, so doing gj on a wrapped
line will jump into an area outside the position [x] and jump back into it
immediately effectively breaking navigation.

Solution: use local mappings that just do the usual h/j/k/l dance.
