The Introduction to Komodo IDE screencast is a great starting point for new Komodo users and for programmers looking to switch to Komodo. From the toolbox to configurable syntax highlighting, Troy Topnik demonstrates some of the key features of Komodo IDE, including code intelligence (autocomplete and calltips) in multi-language files, customizable key bindings and Vi emulation, configurable toolbars, and project templates.
I can't find no documentation!
You can use Komodo's toolbar, there is a blue word icon with a drop-down menu to the right, this drop-down menu lets you choose the browser you'd like to preview the file within.

If the page location on the webserver is different to the file location, you may want to set up a URI mapping, so Komodo automatically translates your file URL into the web URL location:
