The Help documentation can be opened from the GUI using a hotkey (default is set to Cmd+F1 (Mac) or Ctrl+F1 (PC)).
If you want to use a different key combination you can conduct a search for Show Help in the Customize Commands Manager. The first hit will be the command for which a different key combination can be defined.
The corresponding help text will be displayed when the cursor is placed over an object or tag.
If the context-senstive jump does does not work, please use the Search function.
