Pentadactyl is VIM for your Firefox. If you think that the mouse is a productive way to control your browser, think again! It's awesome.

Here some stuff I've learned about it (Still WIP). Please write a comment or message for improvements!

Copy & paste

To copy the URL of the current page, press y. Open a copied URL in the current tab, press p (P for a new tab).

To select text, press i. A cursor appears and you can move to the position you want with the usual commands like (h, j,k,l etc) (maybe you want to search in the page to get to the approximate position). With v you change to select mode and then press Y to copy it.

# Evaluate everything in the array and then find the result:
[1,2,3,4,5,6].map { |z| 
  puts "Expensive operation with #{z}"
  z.to_s
}.find { |s| s.to_i > 1 }

Expensive operation with 1
Expensive operation with 2
Expensive operation with 3
Expensive operation with 4
