# ScrollByPage

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

```lua
local wezterm = require 'wezterm';

return {
  keys = {
    {key="PageUp", mods="SHIFT", action=wezterm.action{ScrollByPage=-1}},
    {key="PageDown", mods="SHIFT", action=wezterm.action{ScrollByPage=1}},
  }
}
```

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:

```lua
local wezterm = require 'wezterm';

return {
  keys = {
    {key="PageUp", mods="SHIFT", action=wezterm.action{ScrollByPage=-0.5}},
    {key="PageDown", mods="SHIFT", action=wezterm.action{ScrollByPage=0.5}},
  }
}
```
