Using both upper- and lower-case letter for trigger-key

[Mark Brethen]

I've written a snippet (named "aview") that will, for example, expand "A" to "AVIEW"; is it possible to expand the lower case "a" into "AVIEW" as well? I believe you can only assign 1 key to a snippet. So I tried it with a second snippet named "aview.1" that assigns the trigger-key "a" but this does not work.
