Emacs Lisp to reload a URL in Chrome (using AppleScript)
View gist:1185476

"Open URL in Google Chrome. I use AppleScript to do several things:
1. I tell Chrome to come to the front. If Chrome wasn't launched, this will also launch it.
2. If Chrome has no windows open, I tell it to create one.
3. If Chrome has a tab showing URL, I tell it to reload the tab, make that tab the active tab in its window, and bring its window to the front.
4. If Chrome has no tab showing URL, I tell Chrome to make a new tab (in the front window) showing URL."
