TemplateWizard can be enabled via a toolbar (new or old). However, the 2003/default wikitext editor doesn't have toolbars as later wikitext editors, like the 2010 version, have. How do I enable TemplateWizard without enabling or using the toolbar?
We will need to figure out how to load the script in the first place. And such a keyboard shortcut will need to be made discoverable somehow. On the whole, I don't think this is a bad idea but Community Tech has more things to work on.
