ScrollByPage

Adjusts the scroll position by the number of pages specified by the argument. Negative values scroll upwards, while positive values scroll downwards.

local act = wezterm.action

config.keys = {
  { key = 'PageUp', mods = 'SHIFT', action = act.ScrollByPage(-1) },
  { key = 'PageDown', mods = 'SHIFT', action = act.ScrollByPage(1) },
}
Since: Version 20220319-142410-0fcdea07

The functionality described in this section requires version 20220319-142410-0fcdea07 of wezterm, or a more recent version.

You may now use floating point values to scroll by partial pages. This example shows how to make the PageUp/PageDown scroll by half a page at a time:

local act = wezterm.action

config.keys = {
  { key = 'PageUp', mods = 'SHIFT', action = act.ScrollByPage(-0.5) },
  { key = 'PageDown', mods = 'SHIFT', action = act.ScrollByPage(0.5) },
}
