Required methods

fn on_internal(
    &mut self,
    w: &mut W,
    internal_exec: &InternalExecution,
    input_invocation: Option<&VerbInvocation>,
    trigger_type: TriggerType,
    cc: &CmdContext,
    screen: &mut Screen
) -> Result<AppStateCmdResult, ProgramError>

execute the internal with the optional given invocation.

The invocation comes from the input and may be related to a different verb (the verb may have been triggered by a key shorctut)

fn get_pending_task(&self) -> Option<&'static str>

fn display(
    &mut self,
    w: &mut W,
