Alt arrow keys print extra characters #3101
Description
Terminal Version: 0.5.2762.0
Microsoft Windows [Version 10.0.18362.356]
Steps to reproduce
Open terminal. Press alt-up, alt-down, alt-right, alt-left.
(For byobu: start byobu with 'byobu'. Press F2 to add a new tab. Press alt-right and alt-left to switch between tabs.)
Expected behavior
-
When not running something like byobu perhaps the letters ABCD should be printed out.
-
When using byobu to manage console sessions it should switch between tabs.
Observed behavior
- c:\windows\system32\bash.exe: ABCD is printed out as expected.
- c:\windows\system32\bash.exe in byobu: Byobu tabs are switched on alt-left and alt-right. (Only a single session is running so alt-up and alt-down just error out as expected.) No additional characters are printed out, as expected.
- Windows Powershell terminal (run->powershell): Nothing is printed out. (Expected? I don't know.)
- Terminal App powershell: ☻♠♦ is printed out.
- Terminal App ubuntu: A◘B☻C♠D♦ is printed out.
- Terminal App ubuntu in byobu: Byobu tabs are are switched as expected, BUT when alt is released one of ◘☻♠♦ is printed out depending on which arrow key was pressed last.
