## Hotkeys

Currently, mrViewer does not yet allow you to redefine your hotkeys, albeit this limitation will certainly be lifted in the near future.
The default hotkey configuration is the following:

W | Toggle Wipe Mode This mode allows you to compare two movies or sequences side by side. The wipe toggles between vertical, horizontal and no wipe. The Hud can display the mode you are in. First, select a background (BG) image from the Reel Window and turn off EDL mode if present. To wipe, press the key and move your mouse in the direction of the wipe. To exit the wipe, press the LMB.
