Is there a way to select text between spaces? (e.g. selecting a complete url http://www.sun.com )

I know there are commands to "select to start of white space" and "select to end of white space" but they will not work together in multiple selection mode.

I like to put cursor anywhere on the url and be able to select the complete url. Is it possible? Combination of steps are fine since I will be recording a macro for the whole process.
