The "App menu shortcut troubleshooting" page seemed to be somewhat
outdated and lacking in information to facilitate troubleshooting. This
is what I did:
* trying to use consistently "qube" instead of "vm"
* trying to get consistent placeholders as uppercase between brackets
* the first part now has a title and distinguishes the GUI from the CLI,
when needed, it is referred to in the following part, instead of
repeating it.
* when a shortcut is missing, add a way to check it from the qube, to
get a better understanding of the problem ("Unavailable desktop
entry")
* the example of a desktop entry is simplified to its bare minimum
* "Fixing shortcuts" is replaced by a more accurate title. Not sure if
this part is still useful.
* mention that `my-old-vm` becomes `my_dold_dvm`
* removed an off-topic comment on Windows HVM and a missing (old?) script
* new part about how to troubleshoot a shortcut that doesn't do anything
Todo:
* update the screenshots
* is the "custom entry" still useful ?
* "Behind the scenes" could be developed
