Add more keyboard shortcuts using hotkeys

[its-me-abhishek]

Is your feature request related to a problem? Please describe.
We had earlier added some keyboard shortcuts, for easy navigation across the task panel. It would be great to extend it further.

Describe the solution you'd like

1. Currently, clicking 'e' key opens up the Task Dialog, we can extend it to use enter and space, as well.
2. Use ArrowLeft and Right to move to Previous and Next Task pages.
3. Use ArrowLeft and Right twice (in a short span, like a double click) to move to the first and last pages as well!
4. Extend the Hotkeys functionality to TaskDialog as well, so as to be able to select/navigate through task fields (which we can, using scroller) and be able to toggle the edit buttons as well, preferably, enter button to select the edit key, arrow up/down to move across fields, backspace (not esc as it is used to close the panel) to stop editing OR enter to complete editing.
5. Can extend the existing hotkeys func or add new one in TaskDialog
6. Adding tests for the same
