Only a double-click on type from another tool records the tool Escape and
Cmd+Enter return to, and the Type tool keeps it until another tool is
chosen. Choosing the Type tool from the toolbar records none, so Escape
goes to the Selection tool. The type and UI checklists and the doc
comments on prev_tool, end_editing and claims_key now say so.
docs/type-parity.md held four copies of the point, area and path type
row, three of them with older Escape wording. They are one row again,
with the Type Orientation sentence that only one copy had.
