# psmux Issue #121 (follow-up) — Shift+Enter PSReadLine compatibility
#
# Tests that modified Enter key bindings (S-Enter, M-Enter, C-Enter) can be
# bound and that send-keys delivers them correctly — both through VT encoding
# and via native WriteConsoleInputW injection on Windows.
#
# Run: pwsh -NoProfile -ExecutionPolicy Bypass -File tests\test_issue121_shift_enter.ps1
