I have wrote many scripts to automate the work in macOS. This one is the most freqently used one. The script can capture the current selection in frontend most app in OmniFocus, and I can jump back to the app using URL.

It is a headache to find an available keyboard shortcuts in Mac OS X. I used Option + Letter and Shift + Option + Letter before, since they are preserved for inputting special characters. It has some problems:

• Emacs and terminal require a modifier for Meta. I choosed Command. It means if I want to use application shortcut with Command in these applications, such as Command+Q to quit the application, I have to use the right one.
• I always forget the shortcuts. Although I have listed them in a sheet, it is a pain to keep it synchronized with the shortcuts defined every where.

I switched to a new solution using keystroke sequence shortcuts recently. All my global shortcuts start with Command+M (⌘M). A menu is displayed when I typed prefix. If I forget the shortcut, I just need to glance through the menu.
