Fix #134

[lambdalisue]

Fix #134. Could you check it?

In my environment, text of the following keys are empty.

• Up/Down/Left/Right
• F1-F12
• Home/End/PageUp/PageDown
• Insert

And the following keys are control characters (such as \r)

• Backspace/Delete/Enter/Tab/Escape

And the following keys are actual text

• <
• \

And I think Vim does not support <S-lt> or <S-Bslash> anyway (not confirmed).

The follwoings are special keys without / with SHIFT keys in Ubuntu 16.04 gnome desktop 64 bit with 106 JP keyboard.
