For programmers coming from other editors, Sublime Text supports TextMate bundles (excluding commands) and Vi/Vim emulation. The unofficial Sublime Text documentation makes disparaging and incorrect remarks about emacs users — me, for example — but I'll overlook them. Why does the unofficial Sublime Text documentation even exist? For one thing, the official documentation is less than complete — much less.
When I said "nearly instant navigation" earlier I meant it. For example, to jump from the current location on the screen to the definition of getResponseHeader in ajax.js, I can type Command-P on a Mac or Ctrl-P on a PC, then aj to open a transient view into ajax.js, then @grh and Enter to open a tab with getResponseHeader selected. Sublime Text is able to keep up with my typing. It feels as responsive as some of the best old DOS editors such as Brief and Kedit.
Once I've selected getResponseHeader, I can find all usages of the function in context by typing Shift-Command-F on a Mac or Shift-Ctrl-F on a PC, then Enter. A new tab will show me the search results with the search term boxed in each five-line snippet. Double-clicking on boxed text brings up the full file context in a new tab.
Clicking on a file name in the left-hand Folders sidebar brings up a transient tab showing the file's contents. Clicking on a different file replaces that tab. Here again, Sublime Text is able to keep up with my typing and clicking. Similarly, the reduced-size navigation on the top right of the page lets me move within a file nearly instantly, without the overhead of scrolling. I wish Microsoft Word were as responsive.
Multiple selections and column selections make quick work of the sorts of annoying edits that used to require regular expressions. Do you need to turn a list of words into a JSON structure where each word is surrounded by double quotes and each quoted word is separated from the next by a comma? It takes about eight keystrokes in Sublime Text, no matter how many words you have in the list.
On my Windows development box, I use two wide monitors. On my MacBook, I use the Retina display plus a Thunderbolt display. Unless I'm editing on one display and debugging on the other, I usually want to see a lot of different source files and different views into source files simultaneously. Sublime Text supports multiple windows, split windows, multiple workspaces per project, multiple views, and multiple panes containing views. It's fairly simple to use all my screen real estate when I want to, and to consolidate when I need to make space for debugging and testing.
