Click on the assigned key in the "current hotkeys" box, selecting it will enable the remove button. I would just go ahead and hit the new button and create hotkeys from scratch using this code. The example below switches the camera view to the right side. Code: // To act on it, we need to know what panel is currently active string $panel = `getPanel -withFocus`; // Try to change the bookmark ONLY if the active panel is a modeling view if(`getPanel -typeOf $panel` == "modelPanel"){ // you can change "-rightSide" flag to any of the appropriate bookmark flags // for the other hotkeys viewSet -rightSide `modelEditor -q -camera $panel`; } For the front/leftSide/back etc flags check the command page https://download.autodesk.com/global/...s/viewSet.html
