Hi guys,
We've bundled Textmate keymap in new RubyMine's EAP (build 500). If we forgot to remap any RubyMine's action to Textmate's shortcut feel free to report about it!
Is there a keyboard shortcut reference card for the TextMate mapings, like for the Default Keymap?
No,
But you can find all shortcuts in "RubyMine | File | Settings | Keymap" dialog. Just choose keymap, find action in tree (or using search field) and shortcut will be displayed in "Shorcuts:" section
