"Hot keys" are alpha-numeric keys you can tap at various points when using Giocoso to achieve various things or invoke particular bits of functionality. You will see all sorts of hot keys indicated in the main Giocoso program display, of course: when you're playing music, for example, the bottom of the screen displays this sort of thing:
...which tells you precisely what tapping the A, T, P and S keys do. The top of the screen similarly displays options for selecting the Play Music, Database Administration, Reports and so on menus. These are obvious hot keys.
In this short article, however, I'm not interested in listing hot keys which are clearly indicated and explained on the main program displays in this way. Rather, I want to list the "hidden" hot keys which do things, but for which no indication is given even for their mere existence!
As of Giocoso Version 3.30, therefore, these hidden hot keys are:
M - Launches the Mgiocoso control panel application
G - Launches a secondary non-music-playing instance of Giocoso (so you can reports, for example, whilst music is playing in the initial session)
B - Launches the Sqlitedbbrowser program (to query and manage a local, Sqlite database) if it has been installed on your system. Giocoso checks for its presence and launches it if it knows it's been installed. If it happens, tapping 'B' simply brings up a message advising you to install the program yourself. You'll need to use your distro's innante package management features to accomplish that (on Ubuntu, for example, a simple sudo apt install sqlitebrowser will usually do the trick).
V - Invokes the ALSA volume mixer, allowing you to alter playback volume (or alter left/right balance etc)
Q or X - Quits Giocoso immediately, without going via a menu option first
F - Only available during music playback. If music is playing, the 'F' key opens your system file manager in the folder that the playing music comes from (so you can, for example, open the booklet PDF that you might store in the same folder as the FLACs)
K - Only available during music playback. If music is playing, the 'K' key will search through the currently-playing folder for a file called 'booklet.pdf' and, if present, will open it in your system's default PDF reader. If no such file exists, then the K key does nothing at all, and no warnings are given.
Note that all hot keys are case-insensitive. Whether you tap 'K' or 'k', for example, is irrelevant: the function the key performs will be invoked just as successfully either way.
