 ## DESCRIPTION
 
 Gets the key bindings for the PSReadLine module.
 
-If neither -Bound nor -Unbound is specified, returns all bound keys functions.

+If '-Bound' is specified and '-Unbound' is not specified, only bound keys are returned.

+If '-Unbound' is specified and '-Bound' is not specified, only unbound keys are returned.
 
-If -Unbound is specified and -Bound is not specified, only unbound keys are returned.
+If both '-Bound' and '-Unbound' are specified, returns all bound keys and unbound functions.
 
-If both -Bound and -Unbound are specified, returns all bound keys and unbound functions.
+If '-Chord' is specified, returns the specific bound keys.
