Backspace, Control-h, and Delete may be typed to erase the character just before the insertion point, Control-W erases the word just before the insertion point, and Control-u clears the entry.  For entries that are too large to fit in the window all at once, you can scan through the entries using the scrollbars, or by dragging with mouse button 2 pressed.  Click the \"OK\" button when you've seen enough."
