I need some clarifacation of exactly what makes blank spaces.
I read to use em-space characters. How do you make em-space characters? Would I use them to center the countdown (5-4-3-2-1) on the screen?
I am also having trouble placing lyrics(4 lines per page) so when the last word on line 3 has a short pause after it (before you tap the next words on line 4) the program leaves line 4 and scrolls in new lines 1 thru 3. This confuses the singer because the next line to be highlighted is line number 4 (at the bottom) and the screen showes lines 1 through 4. I tried using ^ after the long pause word but this is a hit and miss situation. After trying it and tapping in the song, I get to the another part and find I have the same problem at different spot. What would be the best solution that would give the highest chance of getting it right the first time? To start a new page, must the ^ be placed on a new line or can I just put it after the last word where I want the new page to start?
Thanks for any help you can provide.
