Searching in the Help menu has always been a useful way to find things, but in Keyboard Maestro 8 it is a whole lot more useful. As well as searching all the menus, it will search the wiki and return matches there, so functions and tokens can such will all get direct help links.
Unfortunately, the help system only shows the first 20 or so entries, but you can still select the Show All Help Topics at the bottom to go directly to the wiki.
Don’t forget that holding down the option key while selecting from a menu will often get you help on the wiki for the selected item (trigger, action, functions, and tokens).
In any Mac application, pressing Command-Shift-/ activates the Help menu and the Search field will have focus for typing. This was added in OS X 10.8, I believe. If you’d like a different keyboard shortcut, the default can be changed in System Preferences > Keyboard > Shortcuts > App Shortcuts > All Applications.
I can also confirm that the Shift-Command-/ shortcut invokes the Help menu with the search field highlighted, even in High Sierra. I also discovered that pressing it twice will do the same even if the menu bar is hidden (the first press brings the menu bar down, the second press invokes the Help menu’s search field).
Whatever you guys say. Command-Shift-/ opens Safari Help or the Keyboard Maestro User Manual for me. Must be some setting somewhere, or a keyboard setup or whatever. Maybe it’s my CODE Keyboard. Shrug.
