It is worth noting, there are two 'keepass' packages in the repos, and you will want to get the one named 'keepass2' - as that is the one KeePassHttp interacts with. Whilst the direction is based on Ubuntu, I'm sure you'll be able to pick up the difference on your preferred platform. Keep following on for steps on how to use this. And then another project, chromelPass, which interfaces with KeePassHttp to retrieve/update entries in the keypass database, direct from the browser. upon a bit more digging, I discovered there is a project called KeePassHttp, which exposes the database entries over a little HTTP server.

It's quite neat as well, but I went in a different direction. In my limited testing, I only had success with this when specifying which window to map to (which is based off the window title).

This key sequence is a shortcut that you can type so that if you're in the target window, the specified key stroke will be executed. For KeePass this works - custom field & keystroke sequence (need to focus the WS item first)
