### 🔲 To Do
---

#### Cursor Movement
- [x] `←` `→` — move one character at a time
- [x] `Alt+B` / `Alt+F` — jump one word left / right
- [x] `Ctrl+←` / `Ctrl+→` — same as Alt+B/F (alternate terminal sequences)
- [x] `Home` / `End` — jump to start / end of line
- [x] `Ctrl+A` / `Ctrl+E` — same as Home/End (Bash-style)

#### Editing
- [x] Printable characters — insert at cursor position, not just append
- [x] `Backspace` — delete character to the left
- [x] `Delete` — delete character to the right (forward delete)
- [x] `Alt+Backspace` / `Ctrl+W` — delete whole word to the left
- [x] `Alt+D` — delete whole word to the right
- [x] `Ctrl+K` — kill everything from cursor to end of line
- [x] `Ctrl+U` — kill everything from cursor to start of line

#### Selection
- [x] `Shift+←` / `Shift+→` — grow / shrink a text selection
- [x] `Shift+Home` / `Shift+End` — select to start / end of line
- [x] Typing while text is selected — replaces the selection
- [x] `Backspace` while text is selected — deletes the selection

#### Visual
- [x] Live trailing whitespace highlighted in red background as you type
- [x] Text selection shown with reversed colors


#### History
- [ ] `↑` / `↓` — scroll through previous commands
- [ ] `Ctrl+R` — reverse search through history (type to fuzzy-find a past command)
- [ ] Persist history to `~/.rawline_history` so it survives between sessions
- [ ] History deduplication — don't save the same command twice in a row

#### Autocomplete
- [ ] `Tab` — complete current word from a list of known commands or keywords
- [ ] Cycle through multiple matches with repeated `Tab` presses
- [ ] Dropdown menu of suggestions rendered below the input line
- [ ] Fuzzy matching — doesn't need to start with the same letters

#### Multiline Input
- [ ] `Alt+Enter` — insert a newline without submitting
- [ ] Smart indentation — auto-indent next line based on previous

#### Syntax Highlighting
- [ ] Plug in [Pygments](https://pygments.org/) for real language syntax highlighting
- [ ] Highlight matching brackets / parentheses when cursor is near one

#### More Shortcuts
- [ ] `Alt+C` — capitalize current word
- [ ] `Ctrl+Y` — yank (paste) last killed text from `Ctrl+K` or `Ctrl+U`
- [ ] `Ctrl+_` — undo last edit (with a full undo stack)


#### Clipboard
- [ ] `Ctrl+C` on a selection — copy to system clipboard
- [ ] `Ctrl+V` — paste from system clipboard
