A good UI trick that Microsoft came up with (in their office suite) was the regular "paste-clipboard" and the all encompasing "paste-special".  The "paste-special" would bring up a dialog that would further inquire which type of application specific pasting is required.  That type of scheme for special purpose actions would be good.

However, I think a standard naming scheme would also prove benificial and less frustrating than a hundred dialog boxes.  I.e. the format "action-application" using Alex's example would always be "paste-column".

If Gnome is going to establish a central key binding repository, they should be related to general applications.  If an application has further specific actions that need binding, then they would use a local binding scheme.  In the event of a conflict, the application would change what the modifying keys are.

for example:
Ctrl+V = "paste"
an application wants to add the action "validate", and because it was devoped by someone who is not used to the normal key binding wants to use Ctrl+V as well.

The resolution is that the conflicting app specific binding Ctrl+V = "validate" is automatically reassigned to Ctrl+Meta+V = "validate" or some such equivalent.  (obviously this needs to be reflected in the menus--another axample of why hard coding is bad).
