[Feature] Improve key value selection

[SetTrend]

Describe the problem this feature would solve

As a programmer, I'm rather focussed to handle apps using the keyboard than using the mouse or other gesture device. That's why I'd like to suggest to improve accessibility of the 2fast app by adding more keyboard shortcuts. This would ease handling a lot.

Describe the solution

1. When the app opens, the list of registered clients should receive focus from the beginning.

2. The list of registered clients should be scrollable using cursor keys, like UP ARROW / DOWN ARROW / HOME / END / PAGE UP / PAGE DOWN.

3. Hitting ENTER (or RETURN, resp.) should copy the corresponding list item's current value to the clipboard:

   

4. Moreover, hitting any of the number keys (1 to 0) should copy the corresponding list item's current value to the clipboard:
   
   This way, the first 10 list items' values can easily and quickly be copied.

5. Finally, I suggest the clickable area for copying a list item's value to be extended to encompass all three StackPanel items:

   1. The current value
   2. The copy icon
   3. The countdown icon

   
   This will make it easier to copy the current item's value using the mouse or similar gesture device without giving it too much thought.

Thank you for the corresponding suggestion :)

The implementation would be done in several steps, as the implementation of copying the code with tab and enter was easy to implement at first.

The start and order of tab navigation is something i need to look at, this will probably require an option in the settings to not change the operation by default for ease of use or for the controller.

Marvellous job! Thanks!

Today I updated to the latest version. I looks like none of the changes you described is available in the production version yet?

The change was implemented after the release of current version 1.2.6, this will definitely be included in the next maintenance update 1.2.7.
