jj-slice will let the user operate on the boundaries between changes. I'm trying to match some semantics from typical JJ tooling while also integrating some niceties from Helix:
j/k: move up/down one positionJ/K: move to the next nearest boundary up/downCtrl+j/k: on a boundary, drag it up/down one positiongg/ge: go to the first/last position in the rangegw<short ID>: go to the position before (after?) the given change ID (configurable?)space: toggle boundary at positionenter: toggle boundary at position and move down one positionb: set explicit bookmark for chunka: toggle all positions consistentlyc: confirm selectionq: quit?: show help
Perhaps
gwshould select the actual change you're on, and not allow any boundary-wise operations until youj/kto the next/prev boundary?
