# NOTE(smblott). Ultimately, all of the FindMode-related code should be moved to this file.
# When we use find mode, the selection/focus can end up in a focusable/editable element. In this situation,
# PostFindMode handles two special cases:
# 1. Be an InsertModeBlocker. This prevents keyboard events from dropping us unintentionaly into insert
# mode. This is achieved by inheriting from InsertModeBlocker.
# 2. If the very-next keystroke is Escape, then drop immediately into insert mode.
#
class PostFindMode extends InsertModeBlocker

super
name: "post-find"
singleton: PostFindMode
element = document.activeElement
return @exit() unless element and findModeAnchorNode
# Special cases only arise if the active element can take input. So, exit immediately if it cannot not.
