If you have a Roku Voice Remote (https://www.roku.com/products/accessories) you can just say the same of the channel or the channel number into the remote. (if watching LiveTV on the Roku Channel).
The Roku Mobile app (https://support.roku.com/article/217288467) allows you to both use the Voice feature as well as typing the channel number using the virtual keyboard feature.

The idea of a little popup on the screen though is a great idea. 👍
