Pressing and holding the Super key should display numbers [1-9] on the dock icons before pressing any number key

[Amr Ibrahim]

Currently, this feature is incomplete, pressing and holding the Super key should display numbers [1-9] on the dock icons before actually pressing any number key.

Steps to reproduce the bug:
1. Press and hold the Super key
2. Notice that no numbers appear on the dock icons
3. Press 0 (zero) key while still holding the Super key
4. Numbers appear on the dock icons for 2 seconds then disappear
5. Press any number key [1-9] that corresponds to an icon
6. Numbers appear on the dock icons for 2 seconds then disappear and the app launches

What should happen:
Numbers should appear on the dock icons while holding the Super key before pressing any number key in order to choose which number key to press to launch the corresponding app. I believe that's how this feature is supposed to work. And that's how it is working in Unity7 in Ubuntu 16.04 LTS.

Status changed to 'Confirmed' because the bug affects multiple users.

This is not really much possible right now from an extension without changes to mutter.

However, the dock supports a key combination (Super+Q by default) to see the accelerator numbers, so I hope this is enough to get what you need.

This issue is one of a several reasons why I have continued using 14 and 16.
It still has not been fixed in 20. So now I am reinstalling 16.

Is there a reason not to overlay numbers on the relevant icons immediately then the super key is pressed? Why wait?

Showing the numbers after the number key is pressed is both useless and makes Linux look as stupid as Windows. That's an optic worth avoiding, surely.

When I first encountered this useful feature, in Stupid Windows, where they make no attempt to show the numbers, I immediately wrote the numbers on the bezel of the monitor. Which was slightly OK until Windows shifted the icons.

Super+Q is NOT enough and, worse, it increases the memory burden for people who need to use the keyboard because using the mouse aggravates their RSI.

Please have some consideration for non-mouse users.

May the Ubuntu developers be kind to listen to the bug and at least tell us the reason to take out the already existing useful feture like this in the new releases ?
