How can I load files and exit the program?
If you use the command line, 'vd' should pretty much work as you expect:
$ vd foo.csv
You can pipe in tabular data:
$ find | vd
If the file is not plain ASCII .txt or tsv, you will have to specify the filetype with -f and/or other options:
$ ls -al | vd -f fixed --skip 1 --headers 0
Many data formats are supported, with more being added every day.
How do I quit?
You can just bang on 'q' until all the sheets are gone (there are usually only one or two anyway).
Note: If a prompt or editbox is waiting for input, you may have to press '^C' first.
It requires a bit more dexterity, but Control-Q (aka '^Q') will abort the program quite rudely.
If you wish to be a bit gentler, 'gq' will quit all sheets ('global quit').
 Control-Q is the only builtin command (necessary sometimes during development). All other commands can be overridden.
