Launcher > 1.x no longer has shortcut keys for navigation (e.g. filter image)

Describe the bug Previous versions of Pharo Launcher had keboard shorcuts so that you could easily (via the keyboard) navigate the UI to filter images - tab to the images list and then press enter to launch the selected image. This no longer works in PL2.x

To Reproduce Steps to reproduce the behavior:

Launch Pharo launcher (with a few images already downloaded)
Try to navigate to the "enter image name to filter" text box without using your mouse
If you get to the filter text box (currently have to click on it) - enter "8.0" (or some unique text), now tab to the image list (this works, but if you tab again you are stuck). If you realise the list is selected, you can press down arrow to enter the list (its very subtle - but at least works - and I believe 1.x was like this too)
Use the arrow keys to move to the image you want to luanch, and then press enter to launch it (nothing happens - this no longer works in 2.x)

Expected behavior

Should be able to tab to all top level fields in the UI - the current description box is problematic, you get stuck there
Should have named top level UI elements with an obvious keyboad mnemonic to get to them - eg. The filter list should have text &Filter (&F underlines the F) - so that meta-F takes you to that filter element, and the &Images list - should have cmd-I (or cmd-L) to jump to it, and possible CMD-D - for description
pressing Enter on a selected image should launch it

Screenshots N/A

Version information:

OS: ALL
Version: 2.x

Expected development cost ~1 day - should have been carried over from 1.x as this work was done in it. May have implicatations that Spec2 doesn't support keyboard mnemonics?

Additional context Look at how the 1.x launcher works
