Enabling the Group Policy Editor on Windows 10 Home

On Windows 10 Home edition, there is no Local Group Policy Editor (gpedit.msc) and no Local Security Policy Editor (secpol.msc). These tools are reserved to Professional editions of Windows.

It is however possible to install them on Windows 10 Home if you need them.

Open a PowerShell window as administrator and run the following command:

Smart Caps Lock: Remap to Control AND Escape (Linux, Mac, Windows)

把 Caps Lock 變成智慧的 Control 以及 Escape ：

單獨輕按一下就是 Escape 。
若按下時同時按著其他鍵，就會是 Control 。

這應該是 Vim 和 Emacs 的最佳解了！(Emacs? Bash 的快捷鍵就是 Emacs 系列的)

Send Escape if you tap Caps Lock alone.

Installing and configuring dwm on OS X

Install XQuartz (http://xquartz.macosforge.org) which is the development version of the X11.app that ships with OS X, which means it is way more up to date. I have had some weird issues with X11.app v. 2.3-something. XQuartz 2.5.0 fixed that.
Install dwm from Homebrew, brew install dwm. This makes a bunch of necessary tweaks to the DWM configuration.
Add the following script to $PATH, name it dwm-launch and chmod 755:
```
cd ~
```

while true

	#Requires AutoHotkey v2
	; Install the keyboard hook to capture the real key state of the keyboard
	InstallKeybdHook(true)
	; Disable the CapsLock key
	SetCapsLockState("alwaysoff")
	; Send esc key when Capslock is pressed as default
	g_DoNotAbortSendEsc := true

	$*Capslock::{ ; Capture CapsLock key press
	global g_DoNotAbortSendEsc ; use global variable g_DoNotAbortSendEsc
