Navigating pictures with cursor keys

[Mercbac]

I noticed that if I navigate through my pictures in Big Icon view by just using cursor keys, I can press "cursor right" once more after being on an icon on the right-hand side of the screen. This causes the triangular "down" button below the picture icons to become highlighted and pressing enter will then scroll the icons one page down. From that moment on, the cursor keys only let me swap between the up and down triangels, but I can not get the selection frame back on any of my pictures by just using the keyboard. If I use the mouse to click on a pictures and then "escape" out of it back to the Big Icon view, I can navigate the pictures again with the cursor keys.

Since I am using an iMON remote which emulates keystrokes, I would like to have a way to use the keyboard to get back away from those up/down triangular buttons and on to selecting pictures again.

Hope I haven't missed something really really obvious now...
