How can I select text in text editors with the Shift+Arrow keys?

PROBLEM DESCRIPTION or QUESTION

Is there any way to turn on select text with shift+arrow keys in text editor (nano, micro text editor for example)?

Currently the Shift+Arrow key sequences are not mapped in Xshell
You need to add or change the key sequences in the Key Mapping list.

The key values should be set as:
Shift+Left : \033[1;2D
Shift+Right: \033[1;2C
Shift+Up: \033[1;2A
Shift+Down: \033[1;2B
