Using right and left arrowkeys as keybinding does not work properly

[Lattitude75]

I used the following in keybindings file:

main_window.next_page=Right # Next page
main_window.previous_page=Left # Previous page

So, shift+right or left works, even though I could not figure out how to do it without the shift key. And, the page change does not work in the help pane or the thread_view. It only works in the pages for thread_index.

I tried to check if the same is the case with any other shortcuts:

main_window.next_page=] # Next page
main_window.previous_page=' # Previous page

But, these woked perfectly fine.

I am accustomed to the arrows more than the vim keys, so I prefer to use it this way. Is there an issue with using the arrow keys?
