Here's a link to the macros file.
I've never exported macros before, so it may all go wrong, but what should happen is...
- Download the file somewhere on your Mac
- Inside KM Editor, go to File > Import Macros... and select the file.
You should find that a new group has been installed in your Editor, called TBX7 Cleanup Switcher, and inside this will be 15 new macros.
Everything should be set up to use immediately. Go to Tinderbox and press opt-M and the palette should appear. Either use the mouse to select one of the options, or more usually type the number / letter against the menu name. The palette will disappear.
All the macros inside the Switcher are standard 'Interface Control' macros which simply activate a menu on pressing a hotkey. If you're already using Keyboard Macros, then it's all very basic.
To see the available options for the switcher (e.g. to change its shortcut or how it's invoked) just highlight it in the left column. To change its appearance click on the 'Palette' button.
It should just work. When it doesn't, I'll try to help, but I probably won't really know what's going on as I'm not much of an expert. Someone referred to their use of Palettes on the internet somewhere and I played around till it worked -- can't say I really understand what's going on...
Hope someone finds it useful, anyway.
 EDIT: Just remembered where I first saw the technique - it was in a post by Greg_Jones on the DevonThink forum. Thanks to him for this tip and much else...
