Comments Did you know that you can add custom keyboard shortcuts to toggle between your custom Workspaces? To do this, arrange your panels as desired, then choose Window > Workspace > New Workspace, name your workspace and click OK. Then choose Edit > Keyboard Shortcuts (or Window > Workspace > Keyboard Shortcuts & Menus) Select “Shortcuts For”Application Menus (see illustration below), toggle the disclosure triangle next to Window and scroll down to see your custom workspace. Click in the blank area on the right and add your custom shortcut.
Is there a facility in LR to create custom key short cuts or disable them?
