I’m using my own product from www.keymouse.com (we make custom keyboard/mouse products).
The keys are all fully programmable. One of the easiest ways to program a Macro to a key is to assign it to an F13 to F24 key (since they are typically keys not used by most programs). For example, I may want a key for “Share Screen in Skype”. I could assign it to F15, and then cause Keyboard Maestro to intercept that key and perform a Keyboard Maestro Macro. It works good unless I program the key in the F17 to F24 range, then they behave as described above.
