It's these little things....in Emacs

You know why I continue to use emacs?  It's those little things that DTRT.  So, here I am looking at some octave code and trying to look at a function definition in another file.

% Randomly select 100 data points to display
rand_indices = randperm(m);
sel = X(rand_indices(1:100), :);

displayData(sel);
^Point is here
fprintf('Program paused. Press enter to continue.\n');
pause;

Any other editor, I'd have to do one or the other; Go to File-->Open.... or switch to Explorer view and open the file by double clicking on it.

In Emacs, I just do M-x ffap at point and it simply prompts me with the completed file name and waits for me to hit RET.

Awesome.
