Hey Rich,
I’m afraid I’m not familiar with Helix Rade, but if the issue is an alternative way of being able to easily choose from 50+ macros, one suggestion I can make is to forego the AppleScript button solution altogether and use a palette; specifically, a conflict palette that appears automatically when multiple macros are assigned the same hotkey. I and many others find this a great way to use large sets of macros that don’t lend themselves well to setting unique hot keys for each one. Once a conflict palette is triggered, it can then be used to select the macro you want by clicking on it in the palette, or you can type to filter down to the macro you want by typing the macro’s name. Once you have typed enough letters of a macro’s name to uniquely identify it, it will then be triggered. If you’d like to try this method, I recommend looking into this set of macros I wrote for KM8 that makes it much easier to assign the same trigger to multiple macros: KM8: Copy, Paste, and Batch-Delete Triggers
Another option is to skip the conflict palette step (or use this method in addition to it) and simply type the name of the macro you want, rather than its hotkey. This can be done through popular launcher apps like Alfred and LaunchBar, or it can be handled entirely within KM using the Trigger Macro by Name action.
There are other methods that can make working with large sets of macros easier (like the status menu, or other types of palettes that can be set to appear whenever you’re in a certain app) but I’ll hold off on those for now in the hopes that one of the options I’ve described here sound useful. If you’re not sure how to proceed with any of these options, or they don’t end up resolving your problem, feel free to report back!
