SHIFT	PAGEUP	ScrollByPage(-1)
SHIFT	PAGEDOWN	ScrollByPage(1)

These can be overridden using the keys section in your ~/.wezterm.toml config file. For example, you can disable a default assignment like this:

# Turn off the default CMD-m Hide action
[[keys]]
key = "m"
mods = "CMD"
action = "Nop"

The key value can be one of the following keycode identifiers. Note that not all of these are meaningful on all platforms:

Hyper, Super, Meta, Cancel, Backspace, Tab, Clear, Enter, Shift, Escape, LeftShift, RightShift, Control, LeftControl, RightControl, Alt, LeftAlt, RightAlt, Menu, LeftMenu, RightMenu, Pause, CapsLock, PageUp, PageDown, End, Home, LeftArrow, RightArrow, UpArrow, DownArrow, Select, Print, Execute, PrintScreen, Insert, Delete, Help, LeftWindows, RightWindows, Applications, Sleep, Numpad0, Numpad1, Numpad2, Numpad3, Numpad4, Numpad5, Numpad6, Numpad7, Numpad8, Numpad9, Multiply, Add, Separator, Subtract, Decimal, Divide, NumLock, ScrollLock, BrowserBack, BrowserForward, BrowserRefresh, BrowserStop, BrowserSearch, BrowserFavorites, BrowserHome, VolumeMute, VolumeDown, VolumeUp, MediaNextTrack, MediaPrevTrack, MediaStop, MediaPlayPause, ApplicationLeftArrow, ApplicationRightArrow, ApplicationUpArrow, ApplicationDownArrow.

Alternatively, a single unicode character can be specified to indicate pressing the corresponding key.

Possible Modifier labels are:

• SUPER, CMD, WIN - these are all equivalent: on macOS the Command key, on Windows the Windows key, on Linux this can also be the Super or Hyper key. Left and right are equivalent.
• SHIFT - The shift key. Left and right are equivalent.
• ALT, OPT, META - these are all equivalent: on macOS the Option key, on other systems the Alt or Meta key. Left and right are equivalent.

You can combine modifiers using the | symbol (eg: "CMD|CTRL").

Possible actions are listed below. Some actions require a parameter that is specified via the arg key; see examples below.

Name	Effect
SpawnTab	Create a new local tab in the current window
SpawnTabInCurrentTabDomain	Create a new tab in the current window. The tab will be spawned in the same domain as the currently active tab
SpawnTabInDomain	Create a new tab in the current window. The tab will be spawned in the domain specified by the arg value
SpawnWindow	Create a new window
ToggleFullScreen	Toggles full screen mode for current window
Paste	Paste the clipboard to the current tab
ActivateTabRelative	Activate a tab relative to the current tab. The arg value specifies an offset. eg: -1 activates the tab to the left of the current tab, while 1 activates the tab to the right.
ActivateTab	Activate the tab specified by the arg value. eg: 0 activates the leftmost tab, while 1 activates the second tab from the left, and so on.
IncreaseFontSize	Increases the font size of the current window by 10%
DecreaseFontSize	Decreases the font size of the current window by 10%
ResetFontSize	Reset the font size for the current window to the value in your configuration
SendString	Sends the string specified by the arg value to the terminal in the current tab, as though that text were literally typed into the terminal.
Nop	Does nothing. This is useful to disable a default key assignment.
Hide	Hides the current window
Show	Shows the current window
CloseCurrentTab	Equivalent to clicking the x on the window title bar to close it: Closes the current tab. If that was the last tab, closes that window. If that was the last window, wezterm terminates.
MoveTabRelative	Move the current tab relative to its peers. The arg value specifies an offset. eg: -1 moves the tab to the left of the current tab, while 1 moves the tab to the right.
MoveTab	Move the tab so that it has the index specified by the arg value. eg: 0 moves the tab to be leftmost, while 1 moves the tab so that it is second tab from the left, and so on.
ScrollByPage	Adjusts the scroll position by the number of pages specified by the arg value. Negative values scroll upwards, while positive values scroll downwards.

Example:

# Turn off the default CMD-m Hide action
[[keys]]
key = "m"
mods = "CMD"
action = "Nop"

# Macro for sending in some boiler plate.  This types `wtf!?` each
# time CMD+SHIFT+W is pressed
[[keys]]
key = "W"
mods = "CMD|SHIFT"
action = "SendString"
arg = "wtf!?"

# CTRL+ALT+0 activates the leftmost tab
[[keys]]
key = "0"
mods = "CTRL|ALT"
action = "ActivateTab"
# the tab number
arg = "0"

# CMD+y spawns a new tab in Domain 1
[[keys]]
key = "y"
mods = "CMD"
action = "SpawnTabInDomain"
# the domain ID
arg = "1"
