 ** User configuration
 *Note*: Configuration below will make the ~G-keys~ active only when user is logged-on, as any other key.
 
-We will assign the F-keys we defined in ~config.json~ to any program (this includes graphical programs), or to send a string to active window (using *xvkbd*[fn:1]).
-
-*xvkbd* not only allows to send strings ("hello, World!"), but also modifiers (as ~Control-A~, ~Alt-B~, ~Control-Left~), mouse events (motion, buttons), etc... This is a subset of the *typeout* option of config.json. See ~xbkbd man page~ for more details.
+We will assign the F-keys we defined in ~config.json~ to run any program (this includes graphical programs), or to send a string/command output to active window.
 
 Below are some examples (screenshots from ~Xubuntu 22.10~). We will define the following actions :
 - ~G1~: Activate the *Emacs* main window (whose title is always "*GNU Emacs*").
 - ~Shift-G1~: Launch *Gnome Terminal*.
-- ~G2~ (including with modifiers): Send strings/commands results to active window.
-- ~G4~: Send current date to active window.
-- ~G5~: Assigned to ~Hyper~ modifier: ~G5 + a~ will be ~Hyper-a~, as ~Control + a~ is ~Control-a~.
+- ~G2~ (including with modifiers): Send ~strings~ or ~commands output~ to active window.
+- ~G5~: Assigned to ~Hyper~ modifier: ~G5+a~ will be ~Hyper-a~, as ~Control+a~ is ~Control-a~.
 - ~G6~: Will move the cursor to top-left corner.
 All settings below (except for ~G5~) are configurable in ~Settings/keyboard~, ~Application Shortcuts~ tab, or, for pasting text, via ~autokey~ :
