How can I change the Finder keyboard shortcut command + shift + D to open my Dropbox folder instead of the Desktop folder.
System Preferences > Keyboard > Keyboard Shortcuts > select Application Shortcuts in the left column > click the "+" button > Application = Finder, Menu Title = Dropbox, Keyboard Shortcut = whatever you like > click Add
test it out. worked great for me from Finder
Note that this uses the Finder's "Go to > Recent Folders" Submenu. If the Folder isn´t in the List (and there's no way to keep it there), you won't be able to jump to it.
I can get you most of the way there, but I'm going to say straight off that I don't know how to hijack the shift-cmd-D shortcut. However, if you're willing to settle for a different shortcut...
It should look like this:
I tried to come up with a way to override the shortcut for the Desktop menu item, but I was unable to do so.
So this will get you a hotkey to open your Dropbox folder when you're in the Finder, but it won't be via shift-cmd-D.
Use Spark to run an AppleScript:
In Spark, go to File>New Hotkey>AppleScript and set your settings as such:
(You can also use Spark to run a shell script, but I'd recommend using this method, as a shell script is a bit more complicated)
