OK, it does seem like such a deep product but there always seem like a few new things to learn with vi. Here are some really useful ones. The g and z commands arrived because they were relatively unused. So here’s a quick list of useful ones

• zz. I’ve always know that with H or M or L, you get to the top, middle or bottom of the screen, but how can you redraw so your cursor is in the center of the screen, turns
• zb. Or redraw with the current line at the bottom of the screen
• zt. Redraw with the current line at the top
• z<CR>. This puts the cursor at the top of the windo
• z+

But the big use of z is for folding which kind of makes sense, ‘z’ is kind of a folding character and this only works if you have folds for say a YAML or a program.

• zA. Alternate the fold so, Open a closed fold or vice versa
• zc. close a fold
• zC. Close a fold
• zd. Detete a fold
• zD. Delete all the folds
• zF create a fold for N lines
• zM set folder level to the minimum or zero
• zm subtract one from fold level
• zo open a single fold
• zO open all folds

Finally z is used for spelling in adjunct the ]s and [s which moves to next and previous spelling

• zg – Add the current word to the dictionary
• zG – temporarily mark a word as correct
• zw – Ignore the current word it is wrong but don’t spell check
• zW – temporarily make a wrong word

The g commands are also kind of a hodgepodge of things that are roughly going somewhere and there are lot of good ones that I didn’t know about, but g is mainly for “going somewhere”

• * – the asterisk by itself means search forward for the word under the cursor
• # – the number sign means search backwards fro the word under the cursor
• g* – find matches forward for matches that are not a whole word
• g# – find matches backward for partial matches and not just whole words
• gd – go to the definition of a variable that is under the cursor searching down
• gD – go to definition starting from the the first line of the file
• gf – open the file whose name is under the cursor
• gx – open the url under the cursor
• gm – goto the character in the middle of the screen
• gM – go the middle of the text line
• go – Go the Nth byte in the file so 140go means go to character 140

Then there are commands that print values of characters:

• g8 – print the octal value of the character under the cursor

Then there are command I use a bunch for formatting:

• gq{motion} – this means reformat to that motion where gqq means word wrap that line
• gu{motion} – make under or lowercase along that motion
