a - all of the text object, including whitespace

A
  • w

60
Q

Repeat the last change

A

.

Text objects are more reliable than other motions because you don’t need to care as much about the position of the cursor. The commands with text objects are far more repeatable and work beautifully in tandem with the “.” command.

The “.” command works great with repeaters: ;,nN

61

  1. on top of a search match, it selects the match in visual mode
  2. in visual mode, it extends your current selection until the end of the next match
