Emacs: Indentation Commands
Indent Current Line
- indent current line or region.
Indent a Text Selection
- Indent a region. Select a region first.
- Indent all lines in a region in a fixed way. Press → to move to right or ← to left.
More indent commands:
- Indent current line in the same style as previous non-blank line.
indent-relativeindent current line like previous non-blank line, only if the previous line has more indent than current line.
Force Insert Tab Character
The following method works everywhere (also works in minibuffer).
To insert a literal tab char, press Ctrl+q Tab.
To insert a newline char, type Ctrl+q Ctrl+j.
You need to use the above method to insert these characters, because for example in minibuffer, pressing Tab does name completion and pressing Enter finishes the prompt. In most programing language modes, pressing Enter or Tab also does some auto indenting.
