- [x] Make editor.pos method and use that instead of
- [ ] Add word navigation
- [ ] `.` command
Known bugs:
......@@ -30,4 +31,9 @@ The bug causing these two bugs, is localised to be in position.rs. It resolves b
- [x] When typing the first char in a line in normal insert mode, it wont go to the next char.
- [ ] The modifier keys are only working for one command
- [x] The modifier keys are only working for one command
Solutions:
- Make a struct KeyState storing info on the modifiers active. Add a method `feed` which feeds the keystate with a key, updating it. This should Option<Key>, where a key should be returned iff the key entered was not a modifier
Refactoring:
- Organize into modules
