Selecting a label in the cross-reference dialog with the keyboard

[aparsloe]

I notice that when the cross-reference dialog with its list of labels 
opens, the focus is on a label but it is not selected. Using the up or 
down arrow key selects the preceding or succeeding entry. To select the 
initial entry you have to do up followed by down (or down followed by 
up) -- two key strokes -- or use the mouse. When the cross-reference 
list contains only one entry, as sometimes happens, it doesn't seem 
possible with the keyboard to select the entry to insert it in your 
document. You have to use the mouse.
