# iTerm

## Copy Mode

• This lets you copy text without a mouse

• ⌘⇧C to enter copy mode

• Move around with h/j/k/l

• V to copy by line, C-v to copy rectangles

## Instant Replay

• Go back in time to see old output, even if it was cleared

• Start Instant Replay with ⌘⌥B

## Change Tab Height

• iTerm's minimal theme is great, but the tab bar takes up far too much vertical space:

• This is especially an issue when using the [Retina scaling on a 4k display](/learning/wiki/os/macos/display-scaling), where the effective screen resolution is only 1920x1080. Happily, iTerm has an Advanced setting to modify this, in Preferences → Advanced:

• Using a tab height of 30 makes the minimal theme much nicer, imo.
