I use org file to write project setup history / instruction.

Often have to incrementally write the document, by executing lines.

:line-by-line current
executes code at cursor (on 2nd thought, i could have just created a function so that I can bind a key, so I don't have to switch the mode of operation whether to execute a line or a block of code

"below" would excute codes from cursor line to the remaining lines

i found sending multiple lines are not recognized as multiple commands so i added
:combiner
to do something like cmd1 && cmd2
