IntelliJの隠しオプション一覧
こちらのつぶやきにて発見。長いこと使ってるけど、まだまだ知らない事は沢山あるなーとしみじみ
隠しオプション（Registry）の出し方は、"Find Action->"Include non-menu actions"をチェック->'registry'とタイプ"して「Registry」を選択すると出る。
元ネタは「Live Templateを通常の補完（Ctrl+SPACE）にもリストアップする」で、その設定がこのRegistryにあるらしい（該当項目名は"show.live.templates.in.compilation"）。IntelliJの他のリスト同様、適当な文字をタイプすると近似項目にジャンプするので、お目当ての項目を見つけ出すのにそう苦労はしないはず。
いつからあったのかわからんし、今まで存在を知らなかっので、まあそれなりに自己責任な操作なのだと思う。ただ設定項目みてると、いくつか興味深いのもあるので、好奇心には勝てんよね。:-)
個人的にあって嬉しかったのはこの２つ（以下は、それぞれ設定しなおした値。
| ide.mac.filechooser.native | off |
| ide.mac.filechooser.showhidden.files | on |
たぶんIDEA10くらいからだと思うけど、Mac版でメニューによってはOS標準のファイルダイアログが出るようになったのね。それがあんまり気に入ってなかったので、元に戻せるのは正直嬉しい。でもって、OSの隠しファイルやディレクトリも見えるようにできるってのもGOODだ。
＃Mac版IDEAは設定項目がplistだけじゃなく、こんなのもあったとは思わぬ収穫だった。
→ OSXとSwing(Aqua L&F)って相性良くないよね
Registryの設定項目抜き出しといた。数は少ないけど一部の設定項目には説明文（Description）もあったので、それも載せとく。

*1:Timeout after which currently proccessed command is forcibly cancelled
*2:Redispatch events, lost between actions and dialog show/close
*3:Delay between events generated by the playback runner
*4:If dialog shown as a result of some typing, all key types withing this time will be redispatched after dialog is closed
*5:Automatically analyze clipboard on frame activation, and if there is a stacktrace calls Analyze Stacktrace
*6:Enables list view for change signature
*7:If the number of changed compile time constants exceeds this value, make will start full-project rebuild
*8:Whether to perform initial FS refresh before compilation starts. Need this to detect external changes to output dirs
*9:Enable out-of-process compilation
*10:Heap size value in MB for the compile server process
*11:Interval in seconds between ping requests the IDE periodically sends to server. If server does not receive pings for some time, it shuts down. Specify -1 to disable this feature.
*12:Run javac compiler in external process（allows to run compile server with smaller heap size）
*13:Store temporary data in memory for faster compilation; requires larger server heap size
*14:Additional options for compile server's VM
*15:'Log message to console' breakpoint action will out full stacktrace for the thread that hit the breakpoint
*16:Auto show tooltip on mouse over
*17:Disable transparent toolwindow stripes
*18:Whether IDEA should issue a thread dump when an empty completion lookup appears
*19:Whether IDEA should add a special java agent to the debugged process which allows to hot-swap Groovy changes in some cases
*20:Check for duplicate mnemonics
*21:Record additonal information to make bug reports more informative
*22:Shortcut for forced show tooltip
*23:Specify how many working days changes should be remembered. WARNING: Do not use local history as main version control since it may become corrupted if the IDE hangs.
