I found this here:

http://community.activestate.com/forum/macro-quick-find-highlight

But it was really old and didn't use the much simpler ko.commands.doCommand("cmd_findNextSelected");

Instead it used 2 pages of complicated something or other. Someone posted a modified version to use dblclick, but then didn't update the destroy method to unbind the dblclick which led to oddities at times.

So here's an updated version.

Thank you for this useful macro!

However, I have found that it also activates and pops up the general find-dialog if you double-click in the margin of the editor, i.e. if you folds and unfolds a section too quickly. Any idea how to fix that?

Awesome! Thank you !

thanks Adam. this macro is very nice. This works good for all languages but TCL. In TCL, when you double click on "$var_name", then the complete "$var_name" is selected. What modification needs to be done so that it highlights only "var_name", without "$" symbol.

This macro works on top of regular search feature. As a result, there's the side effect that the last search options are reused. In particular, if "[X] Regex" is set you cannot highlight PHP variables like $foo.
