Keyboard navigation

[haiksu]

This pull request adds keyboard navigation possibility to the block. The user can navigate to the progress bar and visit the activity by tabbing to it and pressing the enter key.

The issue reference (#1) doesn't match (as I developed this originally in gitlab).

Which is worse: no keyboard navigation, or the finger-trap created by this change for bars having many dozens of cells which you need tab through each and every one to get past?

I understand your perspective. Thank you for your response! Initially, this change was necessitated by a group of our customers who must adhere to more stringent accessibility requirements. In this case the missing keyboard navigation was a deal breaker.

My general thoughts are have the 'tab' key get you on and off the bar (important for the Overview page), perhaps focusing the first visible cell, and then pressing left/right arrow keys moves between adjacent cells. However, I haven't had the time to spend prototyping the idea to find all the cases where that won't work.

Sounds good. Thanks for testing the pull request anyway! I'll see if I can find time to improve the request (after the summer holiday).

Hi @haiksu We are a UK University and have the same stringent accessibility requirements. If there is anything I can do to help progress the development please do let me know.
