I try to use my keyboard as much as possible in the edit screen to prevent RSI. However when I use the tab key to browse through the fields I always get lost where I am in the screen. Also because not all fields are playing nicely (almost or completely unusable with the keyboard). To help myself I added some highlight functionality:
Not perfect because the given HTML was hard to work with at some points but good enough for me.
Of course it would be better to have full support for the keyboard. Because it is not working properly for fields a came up with this solution so I don’t get lost.
