Advanced features that you may need from time to time.
Use TAB1 TAB2 … TAB7 to add a row with TAB lines.
Default is 6 lines, so you can just use TAB
Tip: You can use the single line as a separator.
See the TAB row example.
Although this is still an upcoming feature, it could be useful in many cases.
Probably especially in the teaching material. Or maybe just for decoration.
