本記事は ターミナルマルチプレクサ Advent Calendar 2011 : ATND の１４日目です。１３日目は tmuxでマウスを使う でした。端末なのにマウスネタ、いいですね！それでは １１日目の記事 の続きとして開発版 GNU Screen でもサポートされるようになったマウスまわりの設定について紹介したいと思います。
開発版の GNU Screen でマウスまわりのサポートがあることについては以前まとめました。
あらためて ChangeLog を見ると次のようにありますが、具体的にどのような操作ができるかもう少し確認したいと思います。'defmousetrack' and 'mousetrack', to turn on/off mouse-tracking for displays.
It's turned off by default.
With mouse-tracking turned on, it's possible to switch to a region ('focus') using mouse clicks.
It's also possible to select a text region in copy-mode using a mouse click to place a mark and
the scroll wheel to scroll through the buffer.
Additional features might be to allow clicking on window-titles in the caption to switch to that window.
まずは screen(1) を見てみましょう。
copy- Marking: The copy range is specified by setting two marks. The text between these marks will be highlighted. If
mousetrackis set toon, marks can also be set using left mouse click.

当たり前ですが screen(1) と書かれている内容は同じですね。もう少し、こう裏技的なものを期待してましたが。。。
マウスで出来る操作は分かりました。けど私は端末作業でマウスを使うのは負けかなと思っていますので使う場面はほとんど無いだろうと考えていましたが、以外に使えそうな場面が見つかりました。
そう、iPad です。iSSH でのソフトウェアキーボードはさすがに使い辛いので、Ctrl-A :up などとはタイプしづらく、そのような場面においてはタッチするだけで操作ウィンドウを切り替えられることはとても素晴らしいです。iPad で GNU Screen するなら mousetrack は必須です！
おわりに
事前に告知していた記事がまとめきれず、急遽前日のエントリを見て書き起こしたので内容の無い記事でスミマセン。。。しかも人様のエントリネタに便乗して。。。github って手軽に試せるのでいいなと思いました。
