I knew I had seen this somewhere…
All you need to do is install KeyRemap4Macbook.
From the "implicit behavior" section:
Share state of modifier keys with all connected keyboards:
When you are using multiple keyboards, modifier keys are shared with all keyboards.
For example, pressing "shift key on keyboard1" and "space key on keyboard2" sends shift-space.
Yes, it works on other Macs too, not just MacBooks.
Karabiner comes with everything you need—a way to define a shortcut, and a way to move the mouse. The warp-mouse-cursor-position utility lives in /Applications/Karabiner.app/Contents/Library/utilities/bin/.
It has a default setting to warp the mouse to the center of the current window by tapping fn or holding ' or /, but for a customized version, add this to your ~/Library/Application Support/Karabiner/private.xml: (After you’re done, go into Karabiner’s preferences and check the box inside Mouse Warping.)
<item>
<name>Mouse Warping</name>
<vkopenurldef>
<name>KeyCode::VK_OPEN_URL_SHELL_mousetowindowcenter</name>
<url type="shell">
<![CDATA[
/Applications/Karabiner.app/Contents/Library/utilities/bin/warp-mouse-cursor-position front_window middle 0 center 0
]]>
</url>
</vkopenurldef>
<item>
<identifier>private.f14_mousetowindowcenter</identifier>
<name>F14 to move the mouse to the center of the current window</name>
<autogen>
--KeyToKey--
KeyCode::F14,
KeyCode::VK_OPEN_URL_SHELL_mousetowindowcenter
</autogen>
</item>
</item>
With Karabiner's utility, you can use the screen option like this:
warp-mouse-cursor-position screen NUM VERTICAL X_OFFSET HORIZONTAL Y_OFFSET
VERTICAL can be top, middle, or bottom, and HORIZONTAL can be left, center, or right.
X_OFFSET and Y_OFFSET can be numerical values, like +10 or -10. Just be careful to put the arguments in the right order—they seem oddly switched.
(For the front window, just use front_window instead of screen.)
Probably the most popular way, but in order to use it for moving to the middle of a window, you’d need an AppleScript to get the bounds of the current window, then calculate the center, etc.

There is no shortcut for it by default. As a hack, you can create
~/Library/KeyBindings/and save a property list like this as~/Library/KeyBindings/DefaultKeyBinding.dict:Then quit and reopen applications to apply the changes.
~mis option-m, which is bound toback-to-indentationin Emacs.I copied the macro from https://github.com/ttscoff/KeyBindings/blob/master/DefaultKeyBinding.dict.
moveToBeginningOfParagraph:, selectWord:, moveRight:would not work with lines that don't start with spaces or tabs.moveToBeginningOfParagraph:,moveWordRight:, moveWordLeft:would not work with some lines where the first non-whitespace character is a special character.DefaultKeyBinding.dict does not work with some applications like Xcode or Firefox.
