Simulate vertical cursor movement when Holding Spacebar and Sliding up/down by moving cursor about 40 or so characters to left/right.
The addition of hold-and-slide on the spacebar has been great. I know Apple has restricted vertical cursor movement.
A workaround suggestion: I don't know if Apple permits it, but
- if upwards/downwards movement is detected, the cursor moves back/forwards approximately the number of characters in a line, say 40 or so characters. It doesn't really matter if it doesn't end up exactly above where it was, all we need is to go backwards in our document quickly!
- I know there's not much space for downward movement, but there's a few mm, and perhaps if we slide down a few mm and hold, the cursor could keep moving to the right by approx 40 or so characters per each 0.2 second (or so) until you release your finger. Likewise behaviour would occur when you reach the upward limit of movement.
