Hi,

I agree with you. We are planning to expose all the Ornatrix commands in the Hotkey Editor so users can create custom hotkeys for every command and tool. But this is probably for the next major version. 

But, since every Ornatrix brush and tool is now independent of Edit Guides and other nodes, you can add custom hotkeys using the Ox command printed in the script editor. 

In this example, the following command is printed when you activate the Comb brush:

OxLoadPlugin(); catchQuiet ( `OxCombBrushTool oxCombBrushTool1` ); setToolTo "oxCombBrushTool1";

Now you can use this command to create a custom hotkey using Maya's Hotkey Editor:

First create a runtime command:

 

Then assign a hotkey to this runtime command:

 

Almost every action in Ornatrix will print the command in the script editor, so you can use the same steps with Affect Selected Only option, or any other option in Edit Guides. 

The selection brush already has a hard coded hotkey. While the any brush is active, press and hold Shift to temporarily activate the Selection brush.
