Navigation buttons on an Apple keyboard

Navigation buttons on an Apple keyboard

If there is something difficult to understand on a Mac is the operation of the navigation keys for text. I mean the famous button Insert, Home, Page Up, Delete, End and Page Down.

Although there seem to be the same as in Windows not, Page Forward and Back do not move the cursor, just the sight, so that when you go to write something you are returned to the place where you left the cursor.

The start and end keys do not work like Windows. End is actually the key management Down, And Home is not, as might be expected to address key mark up.

It is a bit confusing especially if you're already used to the keyboard of a PC. In this case it is best to change the keyboard configuration.

It's simple. Just create a file on this route ~ / Library / Keybindings / DefaultKeyBinding.dict or modify it if it already exists. What you need to write it is:

{

"\ UF729" = "moveToBeginningOfLine:";

"$ \ UF729" = "moveToBeginningOfLineAndModifySelection:";

"\ UF72B" = "moveToEndOfLine:";

"$ \ UF72B" = "moveToEndOfLineAndModifySelection:";

"\ UF72C" = "pageUp:";

"\ UF72D" = "PageDown";

}

Once done, the text navigation buttons on an Apple keyboard will behave like a PC.

The memory speed of the new AMD GPUs are at 900 MHz. The HD 6500m has an interface for GDDR5 and DDR3 memory. The HD 6300m only uses DDR3 RAM. Both models support DirectX 11, Shader Model 5.0, OpenGL 4.1 and HDMI 1.4a.
