How can I disable "standard nanogallery2 behaviour" for keyboard-keys space, enter, left and right

[phstbw]

Hi,

I like nanogallery2 a lot and use it for a student association to show and tag images on a wordpress-site. Every member of the association is invited to add descriptions to images. For this, I added a custom textarea-element, allowing text input. Here's a printscreen:

The code which creates the textarea:
function zzpImgToolbarCustDisplay( elements, item ) { elements.eq(0).html( "<div><textarea id='txt_zzp_iptc_caption'>" + item.title + "</textarea></div>" ); }
Problem: Users should be able to input text containing blanks and use the left/right keys to move the curser. These keys, however, trigger nanogallery2-actions (space = toggle lightshow, left/right = previous/next slide). Especially the space-bar-behaviour makes it almost impossible to enter text.

Triggering happens in program jquery.nanogallery2.js on lines 10502 ff.

Is there a switch to stop or a possibility to "overwrite" this behaviour? Thanks a lot!
