I recently picked up Light Table for Clojure development and liked it. Form evaluation works out of the box and indentation is better than that in La Clojure plugin for IntelliJ IDEA.

I particularly like the idea of command bar, which allows you to search for Light Table commands by name and execute them quickly. I was already used to IDEA’s key map though (Mac OS X 10.5+ which is more natural to Mac users than the default Mac OS X), and wanted something similar. The setting files are in Clojure so it’s easy to customize. This is what I got so far for user.keymap:

{:+ {:app {"alt-space" [:show-commandbar-transient]}

     :editor {"alt-w" [:editor.watch.watch-selection]
              "alt-shift-w" [:editor.watch.unwatch]
              "ctrl-alt-i" [:smart-indent-selection]
              "ctrl-alt-c" [:toggle-console]
              "ctrl-shift-j" [:editor.sublime.joinLines]
              "pmeta-d" [:editor.sublime.duplicateLine]
              "pmeta-shift-up" [:editor.sublime.swapLineUp]
              "pmeta-shift-down" [:editor.sublime.swapLineDown]
              "pmeta-/" [:toggle-comment-selection :editor.line-down]}}}

Apart from these, I found myself using "pmeta-enter" [:eval-editor-form] and "ctrl-d" [:editor.doc.toggle] most when writing Clojure code. After all they are probably the most essential ones no matter what editor you use :)
