So it seems. I've thought a lot about how to DIY a silicone keypad with labeling and backlight but still have no way to do it. I'm all ears for ideas

What trouble?

They do make oblong snap domes: http://www.snaptron.com/products/standard-domes/e-series/e-series-oblong/

Makes sense to use an oblong one but it depends on what's cheaper. If three regular snap domes are cheaper than one oblong, use the regular size (plus the qty discount if they're all the same). 

Never had any issues with my Zipit spacebar that use 3 domes.
