Go to top line
copy mode
// what it does
In vi copy mode, g runs `history-top`, jumping the cursor to the very first line of the pane's scrollback buffer. Use it to reach the oldest retained output instantly instead of paging up repeatedly.
// shortcut
g
// gotcha
This is a vi-mode binding; in the default emacs table g is instead `goto-line` (it prompts for a line number) and top-of-history is bound to M-<. How far back it reaches is capped by the `history-limit` option.
