I print out the source code, using a huge font as to take up lots of
space, bind it all together, and relax in a bathtub full of warm bubbles
and drink wine while reading the code and scribbling comments in the
margins with a colored soap shard. After falling asleep due to the wine
and warm bath, wake up in a few hours freezing cold, surrounded by soggy
pieces of paper with all of the ink washed off. But my brain has
absorbed it all and I can then resume coding from where I left off.
I use vgrep, that's it, no ctags needed.
Reality isn't romantic, there is no magic solution to hard tasks.
