Support shortcut schemas

[akks]

After normalizing shortcuts we have some free keys and some little disappointed advanced users :)
I propose to add shortcut schema support to JOSM (like NetBens, VisualStudio, etc.) so every heavy mapper can change shortcuts and save them to some file (to load later when he need it).

Here is a patch (alpha-version with some problems), so everyone can help improving its design and logic.

@stoecker: Do you think this should be finished before tested release (to give users ability to create customization files after shortuts remapping)?

[stoecker]

Actually I don't like this at all. Usually only a few hardcore users complain, but majority of users uses only few shortcuts. Adding a feature like this prevents stabilization of the situation. Result will probably be forum entries like "Download this file to get proper shortcuts" and newbies will assume this is really a good idea and do so. And then again we have different sets of shortcuts and no improvement over the situation in the past.

With the current preferences the hardcore users can change their settings, but wont affect any others.

It can be really convenient to have different mappings for different situations (working with country-specific cadastre, etc.).
Now you can not even transfer your shortcuts conveniently to different computer (copy-paste fragments of preferences.xml?)

Maybe we should skip this release to stimulate working with default shortcuts, but the feature is useful in principle, I think (maybe invisible for non-experts).

I use different preferences diretories for different situtations. You probably do not just want different key mappings but also different plugins and other settings. This way you can just create a start file for every situation.

It is even possible to use the same cache by setting the path in preferences.xml

I had no problems with my preferences directory on an usb pen drive. Tested with Debian and Ubuntu and josm.jars from homepage.

Why does Netbeans and other IDEs have this feature? Maybe they are too big to copy)

This is true for a lot of other settings as well. There is already a ticket ##4421 for a regedit-like interface, which allows to load partial configuration sets. If you want to implement this, go on. :-) The file should use JOSM's XML preference format and not a CSV.

Maybe we should skip this release to stimulate working with default shortcuts, but the feature is useful in principle, I think (maybe invisible for non-experts).

This would be a simple extension to system of #4421 by defining a "shortcut" subset of preference-keys to export.

This (#4421) looks really good. I almost started to implement remote-control operations for preferences modification, but this is better...

I feel I can implement it. But then we will add separate button on shortcuts panel for this, OK? :)

[simon04]

Just to clarify the status of this ticket: This is a wontfix?

[akks]

This will be supported by #4421 configuration files and API.

Do we need buttons save/load buttons, selection combobox or context menus in shortcut preferences - should be discussed.
