# Caveats and Known Issues for x3270, c3270, wc3270, s3270, ws3270, tcl3270, pr3287 and wpr3287 4.0

## Linux

- Unity's Terminal app will intercept a number of keys (such as F1) that c3270 needs for 3270 operations. The easiest way to prevent this is to create a profile for c3270, with Shortcuts disabled (from the taskbar, select Preferences from the Terminal menu, then go to the Shortcuts tab and un-check Enable shortcuts). You can also disable or remap individual shortcuts if you find the others useful.

## Windows

- Under Windows 10, the console windows that wc3270 runs in may intercept mouse clicks and certain control keys needed by wc3270 for correct operation. To prevent this, you must explicitly disable several console window options for each wc3270 window. Click on the terminal icon in the upper left of the wc3270 window and select Properties. Select the Options tab, and look for the Edit section. Uncheck Quick Edit Mode and Enable Ctrl key Shortcuts.

## MacOS

- When running c3270 in a Terminal window, the Backspace key performs the Delete() action (deleting the character under the cursor) instead of the BackSpace() action (deleting the character to the left of the cursor). This is corrected through Terminal's Preferences dialog. Under the Advanced tab, select Delete sends Control-H.
