+Vim Tips
+========
+
+Open File Under Cursor
+----------------------
+
+Open the `copyright` file and one of the `.copyright-comments.*` files by either
+running the shell command `vim -O copyright .copyright-comments.gplv2orlater`
+from the package root directory or running from `tmp/src/` the shell command
+` vim -O ../../copyright ../../.copyright-comments.gplv2orlater`.  In the former
+case, run `:cd tmp/src/` within Vim.
+
+Making `tmp/src/` Vim's working directory allows source file names under the
+cursor to be opened, for example using `<CTRL-W>gf` to open a file in a new tab.
+
+File Name Header
+----------------
+
+Record a macro to quickly underline headers by entering `qhyypVr-q` from normal
+mode.  Run the macro by entering `@h`.  Note that such a macro cannot be
+repeated using `.` and that it will clobber the unnamed register.
+
+Common Licenses Paragraph
+-------------------------
+
+Position the cursor on the first of the three quoted lines below and, in normal
+mode, enter `3"lyy`.  Then, those three lines can be pasted in normal mode using
+`"lp` or in insert mode using `<CTRL-R>l`.
