Perform, or check applicability of, an "edit/select operation" on the active pane.
These functions perform an "edit/select operation" on the active pane, or check if this operation is currently applicable.
The active pane will be the one on the same screen as
is non-nil, or otherwise the same screen as the default interface.
These functions find the active pane, that is the pane where keyboard input currently goes. Note that this is not necessarily a pane that is recognized by CAPI. The predicates (those with names ending
) return true if the operation is currently applicable. The other functions tell the active pane to do the operation.
The edit/select operations are implemented by the
generic functions such as pane-interface-copy-object.
It is not an error to do the operation even if the predicate returns false. It will just do nothing useful.
