Is it possible to change BOOL value while debugging in Xcode?

ios5, xcode, xcode4.2, xcode4.3

Solution

In the Xcode debugger where it shows the local var values you can double-click on a value and edit it while you're stopped at a breakpoint too. This can be faster than typing the whole thing in the console.

Problem

Is it possible to change the value of the BOOL from true to false or vice-versa while I'm in debugging mode?
