If you use something like Alfred or Quicksilver on your mac along with Flash Builder, then you might be annoyed by the key mappings in Flash Builder.

I only recently realized that Flash Builder’s Content Assist also uses the same ‘ctrl’ + ‘space’ key combination to make things easier when writing applications.

In order to utilize it, I modified my Quicksilver shortcut but just couldn’t get the hang of it. The muscle memory is harder to let go of I suppose.

Finally, with a bit of free time, I found out where the short cuts are configured and changed them. If you’re like me, then you know how painful Eclipse preference navigation can be.

To change the shortcuts, do the following

Preferences -> General -> Keys

Search for “Content Assist” and you’ll be able to easily modify that shortcut.

I changed mine to “option” + “space”
