I switched from MacOS to Ubuntu this weekend .
I'm used to a functionality I had with MacOS I want for all my apps in Ubuntu.
For any app in MacOS, you can search through the different commands within the app thanks to their names, as follow:
Here for instance, I searched for Close a tab in Chrome. Furthermore, Chrome gives me what is the corresponding shortcut for what I search, if it exists, and where it is in the different panes.
How can I add it to all my Ubuntu apps?
For instance, in LibreOffice Writer, I wanted to search for rounding corners of an image, but I couldn't find it thanks to the app.
If the app developer makes that functionality available, you will find it with F1.
