Repeat Last Change

. — replay the last change. The single most useful key.

Keys: .

The . command repeats the last change — exactly what you did, including any inserted text. It is what makes Vim feel like Vim.

If Vim has a single most-loved key, this is it. . replays the last change. Not the last keystroke, not the last motion — the last change. That distinction is the whole reason . feels magical.

Worked example — .

The single most powerful key in Vim.

Step 1 ·
dot.repeat
Step 2 · cwxxxEsc · cw to xxx, Esc.
cw to xxx, Esc.
Step 3 · j0. · . — same change at new cursor.
. — same change at new cursor.

Dot replays the last change (anything that modified the buffer). Cheap revolution: structure your motions so dot becomes useful.

Step 4 · j0. · . again — third line.
. again — third line.

Move-and-dot is a Vim idiom. Beats keyboard macros for trivial repetitions.
