Struct StepBookkeeping 

pub struct StepBookkeeping {
    pub pending_was_macro_chord: bool,
    pub was_insert: bool,
    pub pre_visual_snapshot: Option<LastVisual>,
}

State carried between Editor::begin_step and Editor::end_step.

Treat as opaque — construct by calling begin_step and pass the returned value directly into end_step without modification. The fields capture per-step pre-dispatch state that the epilogue needs to run its invariants correctly.

Fields

pending_was_macro_chord: bool

True when the pending chord before this step was a macro-chord (q{reg} or @{reg}). The recorder hook skips these bookkeeping keys so that only the payload keys enter recording_keys.

was_insert: bool

True when the mode was Insert before the FSM body ran. Used by the Ctrl-o one-shot-normal epilogue to decide whether to bounce back into Insert.

pre_visual_snapshot: Option<LastVisual>

Pre-dispatch visual snapshot. When the FSM body transitions out of a visual mode the epilogue uses this to set the </> marks and store last_visual for gv.
