[TxMt] Simple (probably) request for UI change in bundle editor

Now let's see if anyone else agrees with this... :-)

Currently in the bundle editor, there's an "Activation" popup menu that has just two items, "Tab Trigger" and "Key Equivalent". Depending on which is selected, a tab trigger or shortcut key is displayed and can be edited in the adjacent text field.

I think it would be clearer, faster, and probably take less space in the UI, to simply show two text fields, one with the tab trigger, and the other with the shortcut key. And I think a significant benefit to someone using a bundle is that it then becomes possible to just move through the bundle items and see the shortcuts in the process. Makes learning a bundle much faster.

Many thanks, Ken
