APPENDIX → TN3270 Key-Mappings

The list of keys below shows how the emulation's keys are mapped to the your local keyboard. This happens automatically when you choose to use the emulation for a connection and is subject to some configuration options of the TN3270 emulation via Options→Session Profile→Emulation→TN3270.

 

However, any of these keys can also be mapped to any other key-combination on the local keyboard via the Options→Keyboard Profiles. They can also be mapped to user-defined clickable screen buttons via (Options→Session Profile→User Buttons). Both functions use names for the keys listed in the table of emulation dependent key names.

Special ZOC Functions

The mappings below perform functions, which are not found on an original TN3270 terminal but which may be especially useful in the context of a terminal emulator, e.g. ZOC offers an undo function like in a local editor or on a text processing program.

ZOC 3270 Function PC Key Comment
[HomeCmd] Alt+[Home] Jumps to the Command ===> field.
[MovePrevWord] Alt+[Left]  
[MoveNextWord] Alt+[Right]  
[DeleteNextWord] Ctrl+Del  
[MoveEOF] Ctrl+[End] Move to end of field.
[MoveBOL] Alt+[Enter] Move to beginning of line.
[SelectAll] Ctrl+A  
[EraseEOF] Ctrl+K Erase to end of field
[EraseField] Ctrl+L Erase entire field.
[SaveCursorPos] Ctrl+S Saves cursor position.
[RestoreCursorPos] Ctrl+R Jumps to previously saved position (also jumps back to the position before [Home] was pressed)
[Undo] Ctrl+Z Undo function similar to using WinWord or a modern source code editor.
[Redo] Ctrl+Shift+Z Revert the last 'undo'.

 

[1] The functions of Return and Shift+Return (also Alt+Return) can be swapped in the settings of the TN3270 emulation via Options→Session Profile→Emulation→TN3270. The combination Cmd+[Return] (macOS only) is unaffected by the swap option there.
