Thanks for the information, especially the use of the 'N' key. That is what I remember.

Using it tells me visually the exact note that I have selected and then I can also use the arrow keys to move the notes vertically. The only thing left that I find awkward is the creation of'Ties'. If I try to tie an eighth note with a quarter note, the tie does note show between these two notes, it simply blobs them into a dotted quarter which is not always how I want to see them with regard to beat timing. Still, the Import/Export XML allows me to easily do all this in Muse.
