How to take defaults in port installs

This is probably a silly question, but is there a simple way to have my ports select all the default options when I run make install? I hardly know what 10% of these options are, and I want my machine to compile away without my babysitting it.
 
I've noticed setting BATCH doesn't work anymore as expected. Setting NO_DIALOG worked for me, it basically makes the config part of the build process to be skipped. For example:

make -C /usr/ports/net/mtr -D NO_DIALOG install clean
