Uh switching on off channel , uh volume ,  okay , that's great.
'Kay. Um um among the findings I found that m m most of the curr mm presently available remote controls also include other mm  functionalities um in their design , like operating a V_C_R_ , but they don't seem to be able to deal with D_V_D_ players , but then  there are  surely there are many other functionali functions that could possibly be added to them , but according to the last minute update um actually um we do not want to have all this complicated functions added to our design.
Mm-hmm.
So my personal preferences would be uh to keep the mm the whole remote control small um just like the physical size. And then it must be easy to use , so it must follow some conventions um like whereabouts you find the on off button and maybe the colour tends to be red or something. Um then   yeah , the must-have buttons would be on off and then  the channel numbers and then um  the one that allows us to go to the next or the previous channel , and then volume has to be there. But then um other functionalities um  could be just  uh there could be a menu button and you could change things on the screen then , um for example brightness and mm similar functions could be just um  done through the menu. And yeah , the last question I had about whether we wanted to incorporate n uh more functionalities , the answer was already no because of the last minute update.
