AppleScript for "spring-loaded" jump to a frequently used app.
#!/usr/bin/osascript
-- OS X script for "spring-loaded" app switching
-- Useful if you have a preferred app for jotting notes and ideas.
-- I use MacVim with Vimwiki, but you can use whatever by changing one line in this script.
-- To make this useful, you need to assign a hotkey.
-- OS X won't let you directly assign a hotkey to a script.
-- You can get around that by creating an Automator Service that runs this script.
-- See http://apple.stackexchange.com/questions/175215/how-do-i-assign-a-keyboard-shortcut-to-an-applescript-i-wrote for how to do that.
-- I use Ctrl-Cmd-B because its not commonly used by other apps. You may need something else.
-- With a hotkey in place, you can press it from within any app and jump to your target app.
-- When you're done, the same hotkey takes you back to your prior app.
