That link didn't work for me, but this does:

I changed to GB keyboard in Firefox in Lubuntu 14.04, but still I cannot 
enter THEN (Shift+3). If I use US or SE keyboard I can enter less. It 
should perhaps be documented that you need to change to GB-keyboard for 
most keys to work. Shift-3 sends £ when using GB keyboard. When I click 
with a mouse on the on-screen touch keyboard nothing happens. E.g. 
holding Shift (on the physical keyboard) and clicking 3 doesn't enter 
THEN. I think it is possible to fix this so that the mouse also works.

Otherwise it's great. I could run ZX-FORTH. A suggestion for improvement 
would be to save the RAM in cookies or Local Storage.
