Open up the Hotkeys panel to access some button alternatives for the main keyboard hotkeys.

You can use these initially if you are unfamiliar with the keyboard hotkeys, or if you simply prefer to use the mouse for everything. Not every action is covered by these hotkey buttons though, so as you become more familiar with UVLayout, you will want to study the full list of keyboard hotkeys below.

The top row of buttons are simple clicks to set the view to UV, Ed or 3D space, adjust the brush size, or Undo (shown as Z, but is really Ctrl-Z).

The remaining buttons are toggled on and off. When enabled, you can then use the right mouse button to apply the selected key at the mouse pointer location. If an action calls for the double-tap of a hotkey (e.g. select edge loop with Double-C) then double-click the right mouse button to do the same thing.

Disable the button to turn off the mouse hotkey action, and then the right mouse button can again be used to zoom the view. To zoom the view while a hotkey button is enabled, use the mouse wheel, or click and drag the left and middle mouse buttons.

To manipulate shells or UV vertexes, you can either manually select the appropriate combination of Space, Ctrl and Shift buttons, or use the buttons under the Hints section to set them up for you.

To temporarily disable the selected mouse hotkey actions, stow the Hotkeys panel. Open it back up and the previously selected mouse hotkey actions will be re-instated.


Contents

Below is the full list of hotkeys that can be used in UVLayout's graphics window. Its split into four different sections, the first being hotkeys common to all viewing modes, followed by the hotkeys specific to each of the UV, Ed and 3D viewing modes.

First off, here's some short-hands used in the lists below:

    LMB - Click the left mouse button.
    MMB - Click the middle/wheel mouse button.
    RMB - Click the right mouse button.
    Ctrl - Hold down the Ctrl key while typing the listed key. The Command key can also be used under Mac OS X.
    Shift - Hold down the Shift key while typing the listed key.
    Space - Hold down the Space key while typing the listed key.
    Double - Double tap the listed key.
    *** - Indicates a hotkey that will switch to rectangle selection, to apply the action to multiple shells, if the mouse pointer isn't currently over a shell.

Note: The hotkeys are case-sensitive. This means that if you accidentally turn Caps Lock on, then most functions will not work correctly. Because of this, a warning message will appear in the 3D window whenever you have Caps Lock on.
