This adds range select ability in two ways: 1) Sticky: like what we already have with the staging view i.e. press v then use arrow keys 2) Non-sticky: where you just use shift+up/down to expand the range The state machine works like this: (no range, press 'v') -> sticky range (no range, press arrow) -> no range (no range, press shift+arrow) -> nonsticky range (sticky range, press 'v') -> no range (sticky range, press arrow) -> sticky range (sticky range, press shift+arrow) -> nonsticky range (nonsticky range, press 'v') -> no range (nonsticky range, press arrow) -> no range (nonsticky range, press shift+arrow) -> nonsticky range
