You should consider 2 “presses” for the pedal:

1) quick press-release: changes mode

2) long press-hold-release: changes mode on press and then changes mode back on release

This allows the user to not have to hold the pedal down if they dont want.

User can specify a time threshold used to determine the difference between a quick press and a long press

Perhaps if it’s released before another key is pressed, the mode stays changed. If another key is pressed first, it changes back on release.

Why not have an automatic transmission instead, like vi goes, hey these haven't been real words for the last 8 characters, bet they were esc commands.

"cruise control" for vi :)
