Some feature requests

[fabius85]

Wonderful tool!
Just got some feature requests you might want to consider:

1. Pass an argument as search keyword to be able to use
   wiki something
   instead of typing

wiki<Enter>
something

2. Different keybindings:

• In keyword search view i would use Escape to quit in addition to Ctrl+C
• In wiki page view i would use Escape or Q to quit in addition to Ctrl+C and maybe Left and/or Backspace to go back to search view.

3. Language selection parameter -l should be mentioned in the help command
