Focus and Input Behavior

When you press mapped keys, 3270Web sends the action to the host and refreshes the terminal content. Cursor-aware behavior is preserved for field input where possible.

Tips for Reliable Use

  • Keep browser focus on the terminal area while typing.
  • Use the keypad for less common 3270 keys if your keyboard layout does not expose them.
  • If commands appear out of sync, pause briefly and retry in debug playback mode.
