Help with removing 'rest' from measure.

Hi.
Im new to muse score and trying to understand how i can remove a 'rest' (not sure of the proper word) from a measure.
Heres a picture of the measure.
I want to remove that rest, and have the remainder of the notes in the measure fill the space it occupied.
How can i do this?
The only way i could figure out was by rewriting the rest into the note i want, but then i have to manually rewrite all the following notes. For one measure this could be ok, but if i had alot of measures written afterwards, that would be not fun. So im sure theres a more normal way to do this...

Also, is there some way of writing in all the notes to a song without muse scores auto correct thing enabled, and then after writing the score to turn on the auto correct and then edit what needs to be done?
