Here’s a quick way to open the file browser with a keyboard shortcut.
Add a new javascript macro. If you aren’t familiar with javascript macros in OpenBuilds control, check out my other posts.
Click on the “Javascript” tab on the left and add this code.
$('#file').click();
Type the keyboard shortcut you want to use in the Keyboard Shortcut field and then click Apply.

That’s it.
