Not exactly a dark secret, but I like to put the following mapping into my .vimrc file, so I can hit "-" (minus) anytime to open the file explorer to show files adjacent to the one I just edit. In the file explorer, I can hit another "-" to move up one directory, providing seamless browsing of a complex directory structures (like the ones used by the MVC frameworks nowadays):
map - :Explore
These may be also useful for somebody. I like to scroll the screen and advance the cursor at the same time:
map j
map k
Tab navigation - I love tabs and I need to move easily between them:
map :tabnext
map :tabprevious
Only on Mac OS X: Safari-like tab navigation:
map :tabnext
map :tabprevious
