Using the "Normal (autoselected)" or "JEI synchronized (autoselected)" search box modes ignore the JEI "show recipe" or "show usages" keybinds (default R and U).

I like the autoselected search boxes, but this is the reason I don't use them. I cannot conveniently search up for existing items unless I search them in JEI first.

On the other hand, this can cause the inconvenience of accidentally showing a recipe when just trying to type R with your mouse over an item. You'd have to move the mouse outside your inventory to use the search box.

This is intended, having to move the mouse to avoid opening the GUIs by accident is annoying.

there needs to be a way to de-focus the textbox so the jei keybinds work again.
