Remapping key to host function

You can remap a key to a host function that is not available by default from the keyboard or remap a combination of keys to a host function, including the Shift, Alt, and Ctrl keys. You can remap a key to a host function because the default key values are not always ideal for all host applications.

About this task

For example, in some panel-driven z/OS® application programs, it is convenient to have a function key to erase the contents of a field, such as Erase EOF. This function is not provided by default, but it can be enabled by remapping a function to a key or combination of keys of your choice.


  1. In the Extension for Terminal-based Applications window, click Keyboard Remap.
  2. Optional: To locate and load the remapping file if you have saved the remapped keys to a file, click Load.
  3. Click Key Assignment tab.
  4. Click Host Functions from the Category list.
  5. Select the function to which you want to remap a given key or combination of keys from the list of host functions.
  6. Click Assign a Key.
  7. Press the key or key combination that you want to remap to the host function. For example, to use Alt+4, press and hold the keys simultaneously for key combinations.
  8. Optional: Save keyboard remapping.
  9. Click OK.

What to do next

Note: Remapped keys retain their custom values during the host session for which the keys were remapped only. The remapping does not persist across subsequent host sessions that are started from other host connection windows.
