go into methods shortcut key in emacs

go into methods shortcut key in emacs

[Pedro Sa da Costa]

Hi,

with this example, i would like to select the method callMethod() inside 
test() method and, by pressing any key (for example, F3), i would like 
to go into the method. How is this possible in emacs?

public void test() {
    obj.callMethod() <-- I would like to select callMethod() and, by 
pressing f3, i go into this method.
}

public void callMethod() {
    System.out.println("Hello world!");
}

Is this possible?

Thanks,
Pedro

It's explained in the chapter "Tags Tables" of the Emacs Info manual;
briefly, you create a TAGS file ("etags" command) and in your buffer,
do M-x visit-tags-table. With point at or behind ".callMethod", you go
to the tag's definition via M-. (find-tag).

All the best!

Because I am too lazy to learn and try out the TAGS features in Emacs
(I have used Emacs since 1997 and never tried that out...) I use C-s
C-w instead. It might take a few more keystrokes (keep typing C-s to
find the correct place) and it might sometimes find too many
occurances, but it works quite well.
