c_CTRL‑O.vim

One-shot normal mode for command-line mode

Overview

This plugin introduces a natural analogue to insert-mode CTRL‑O for command-line mode. When partway through writing a command-line or performing an incremental search with CTRL‑G and CTRL‑T, you might:

• Redraw the screen with CTRL‑O CTRL‑L.
• Scroll around with CTRL‑O zt, CTRL‑O CTRL‑D, CTRL‑O zL, etc.
• Peek at what function or section you’re in with CTRL‑O [[, check whether you’re within an #if with CTRL‑O [#.
• Peek at the definition for the current match with CTRL‑O gd, CTRL‑O gD, CTRL‑O [ CTRL‑I, CTRL‑O CTRL‑], etc.
• Resize the window with CTRL‑O CTRL‑W 80|, CTRL‑O CTRL‑W _, etc.
• Perform a nested search with CTRL‑O /{pattern}<CR>, then peek at subsequent matches with CTRL‑O n.
• Execute nested command-lines like CTRL‑O :se {option}<CR>, CTRL‑O :w<CR>, etc.

Mappings

Command-line CTRL‑O — Execute one normal-mode command, return to command-line mode. Works like insert-mode CTRL‑O.

Command-line CTRL‑\ CTRL‑O — Abandon the command-line, go to normal mode without moving the cursor. This differs from command-line CTRL‑C and <CR> during an incremental search, after using command-line CTRL‑O to move the cursor off of the latest match. Specifically,

• CTRL‑C — Jumps to the original cursor position.
• <CR> — Jumps to the latest match.
• CTRL‑\ CTRL‑O — Does not move the cursor.

The original cursor position is pushed onto the jumplist.

Command-line CTRL‑R CTRL‑O {motion} — Insert {motion} text into the command-line as if typed. The text is also put into the unnamed register.

Command-line CTRL‑R CTRL‑R CTRL‑O {motion} — Insert {motion} text into the command-line literally. The text is also put into the unnamed register. This differs from command-line CTRL‑R CTRL‑O {motion} when the text contains characters like <BS>.
