How do I edit a command in a full Vim buffer before executing it?

Explanation

Pressing <C-f> while on the : command line opens the command-line window, where you can edit your command using full Vim editing capabilities.

How it works

• Type : and begin a command
• Press <C-f> to open the command-line window
• Edit the command using normal Vim motions
• Press <CR> to execute

Example

You start typing a complex substitute command and realize you need to edit the middle:

1. Type :%s/very_long_pattern_name/
2. Press <C-f> to open in a buffer
3. Navigate and edit with full Vim power
4. Press <CR> to execute

Tips

• q: opens the command window directly with history
• q/ opens the search history window
• The command-line window is a regular buffer with special behavior
• <C-c> closes the window without executing
• This is invaluable for editing long, complex commands
