NetBeans is a modular system in which many modules work cooperatively. However, it is not always possible to guarantee a
priori that modules coming from different sources will not make conflicting demands on the platform. A case in point
being the scarce resource of keyboard shortcuts.

This enhancement proposes a graceful mechanism to handle handle the conflicting keyboard shortcut registration.

When a user invokes such a conflicting key binding (sequence), the NetBeans platform detects it and shows a pop up menu
that looks something like this:

Assume that multiple modules registered actions for keyboard shortcut CTRL+D

Go to Tools:Options:KeyMap to resolve CTRL+D
Action 1 (Module 1)
Action 2 (Module 2)
Keep and Action 1 (Module 1)
Keep and Action 2 (Module 2)
CTRL+D prefix...more actions

The user has following choices:

- go Tools:Options:Keymap panel to fix the conflict.
- invoke one of the actions
- keep the keyboard shortcut (CTRL+D) for one of the actions and then invoke that action. Subsequently the selected
action will be invoked
- proceed to the key map with conflicting prefix. The platform will then wait for the user to enter more key strokes
while showing the prefix sequence in the status bar.
