Add some colour to your bidet remote and make it easier the feel the buttons, by adding some coloured vinyl stickers.
I find red and blue make it easier to recognise which is hot and cold.
Whereas green is good for hi-flow. May be use yellow or white for low-flow.
You can also put clear stickers, over the ones that don't have an obvious colour meaning, to make them easier to feel. Handy at night when the toilet light is off.
