How can I use the selection wit h a template? I can use word_selection when I am edition a template but when I am in the editor with some text selected, I can't bring by template with Ctrl-Space. I have to break the selection to do so. How can I use the selection with my template?
You're right, depending on the place you request the completions, the templates won't appear. Please create a bug-report for that. In the meanwhile, for your case it might be worth creating a scripting action to do what you want (it's easy to bind something to ctrl+2+something - see: http://pydev.org/manual_articles_scripting.html.
A simple example close to what you probably want can be found at: http://github.com/aptana/Pydev/blob/master/plugins/org.python.pydev.jython/jysrc/pyedit_import_to_string.py
OK, I did a bug report https://sourceforge.net/tracker/?func=detail&aid=3100367&group_id=85796&atid=577329. I will look at the turn around. Thank you.
