I'd like to have a keyboard shortcut (ideally CTRL+ENTER) that gets me to the target folder when I use it on a shortcut file. I can do that in the left-click menu ("Open target's folder") but I'd like to skip that step.
I've fixed the linked post. An update to the forum software broke a lot of the old posts which use code tags, unfortunately.
For your question:
Select Settings > Customize Toolbars, then click the Keys tab.
Make a new Lister Hotkey:
Click the arrow on the right of the hotkey field to open a menu for special keys like Enter. Hold Ctrl and click Enter in the menu to set the hotkey to Ctrl+Enter.
Set the command to:
Go NEWTAB OPENCONTAINER=target
(Remove NEWTAB if you want it to change folders in the existing tab.)
Finally, click OK in the Command Editor, and then click OK in the Customize window.
