I installed Ubuntu 12.04 LTS in Windows 8.1 using vmware workstation. When I open a file in the terminal using vi filename.c, the arrow buttons will not work properly, pressing up arrow prints A, down arrow B, right arrow C,left arrow D. How can I overcome this problem?

  • What program are you opening? What your describing is perfectly normal behaviour. –  Sep 25 '15 at 08:00
  • Please [edit] your question and add what command you use to open a file in terminal (e.g. nano) and what terminal-emulator (e.g. gnome-terminal) you use. Besides this, are you holding the SHIFT key in the meanwhile? SHIFT+↑ is "A", SHIFT+↓ is "B", SHIFT+→ is "C" and SHIFT+← is "D", that's normal. – Byte Commander Sep 25 '15 at 08:01
  • I use vi command to open a .c files,the shift key is not is working properly. – ramesh Sep 26 '15 at 10:18
  • Look into your shift key – Zuko Sep 26 '15 at 11:43

Your Shift key is probably stuck.

This can happen because either the keyboard key switch is physically stuck a bit or because the last time you released the key the system did not properly detect it.

Both causes should get eliminated by hitting the key a few times.

It's perfectly normal behaviour that the key combinations Shift+↑, Shift+↓, Shift+→ and Shift+← in a terminal window result in the characters A, B, C and D to be printed.
