Support for custom mouse/keyboard handlers

[ruzzle]

Hi there! I am a big fan of D-Tale to do interactive/statistical analysis on dataframes. Really like the rich feature set of the framework.

Currently I am looking for a way to "bookmark" certain records shown within D-Tale and figured that this may require support for custom mouse/keyboard handling. My thoughts here were to have the option to right-click a dataframe record (or selecting it and pressing a hotkey) and trigger (pre-registered) custom handlers (in my case my own function to store bookmarks in a custom location). Is this something that would be worthwile implementing? Or is this already possible (and am I missing something)
