The auto-complete components are in the local iRuler.xml config file. I'll have to get this updated in the next release of the editor, but in the mean time, feel free to add the keys you want yourself. In the Editor, click on the "Tools" menu, and then the "Config" sub menu, and then select "Edit Config". It should start notepad with the configuration file. It should be fairly self-explanatory.
The drop down for the events is working for me so I'll have to make sure that I have the latest code up on DevCentral. I'll try to get to this tomorrow.
Thanks for the heads up and I'll make sure I let you know here after I've got the latest bits on DevCentral.
