tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

	"""A simple addition to Python's optparse module supporting subcommands
	like those found in the svn or hg CLIs.

	To use it, instantiate the Subcommand class for every subcommand you
	want to support. Each subcommand has a name, aliases, a help message,
	and a separate OptionParser instance. Then pass a list of Subcommands
	to the constructor of SubcommandsOptionParser to make a subcommand-
	aware parser. Calling parse_args on that parser gives you the
	subcommand invoked, the subcommand's arguments and options, and the
	global options all in one fell swoop. See the smoke test at the bottom

	# 中西文切換鍵的默認設置寫在 default.yaml 裏面
	# 以下的 default.custom.yaml 在全局範圍重定義該組快速鍵
	#
	# 可用的按鍵有 Caps_Lock, Shift_L, Shift_R, Control_L, control_R
	# Mac 系統上的鼠鬚管不能區分左、右，因此只有對 Shift_L, Control_L 的設定起作用
	#
	# 已輸入編碼時按切換鍵，可以進一步設定輸入法中西文切換的形式。
	# 可選的臨時切換策略有三：
	# inline_ascii 在輸入法的臨時西文編輯區內輸入字母、數字、符號、空格等，回車上屏後自動復位到中文
	# commit_text 已輸入的候選文字上屏並切換至西文輸入模式

	# default.custom.yaml
	# 全局範圍識別輸入串爲 rime + 任意數字序列，以及形如 rimeime-1.2.3 的常用西文短語
	# 也可將本組 patch 寫入 <輸入方案ID>.custom.yaml 使這組規則僅在一款輸入方案中有效
	#
	# 第一例，輸入 rime 之後，再輸入任意一個數字，則立即識別爲西文輸入
	# 再加上 default.yaml 原有的 email 規則，識別包含 @ 字符的郵箱，於是可以一氣呵成 [email protected]
	# 第二例，輸入到 rimeime 時，立即識別爲西文輸入，並可跟隨任意位數字及指定的符號
