🔲 To Do

---

Cursor Movement

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

Editing

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

Selection

• Shift+← / Shift+→ — grow / shrink a text selection
• Shift+Home / Shift+End — select to start / end of line
• Typing while text is selected — replaces the selection
• Backspace while text is selected — deletes the selection

Visual

• Live trailing whitespace highlighted in red background as you type
• 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 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
