To yank or cut, type `y` or `d`, followed by a 'text object'. These describe how much text should be yanked or deleted. For example, `yw` copies one word and `d$` deletes from the cursor to the end of the line. They can also both be used in visual mode, pressing `v` and moving the cursor and then pressing `d` deletes all text inside of the selection.
### Registers
A register is just another name for clipboard. But unlike other text editors, Vim has many of such "clipboards".
To yank or delete to a register, type `"<register name><command>` (e.g.: `"ayw` to [y]ank [w]ord to register `a`). Register names can be only one character long for obvious reasons (`"m`,`"M`, `"3` are allowed, but `"mr`, `"MyReg`, `"MyRegisterName` are not). The default register that is stored to when no register is specified is `"` and the system clipboard that can be accessed in other programs is `+`. You can also use lower case characters to access registers and use uppercase characters to append to registers. For example `"dyy` copies the current line to the `d` register, typing `"D3yw` copies the next 3 words and adds them to what is already stored in `d`.
Pasting can be done in normal mode or in insert mode.
In normal mode:
-`p` pastes after the cursor
-`P` pastes before the cursor
-`gp` pastes after the cursor and moves the cursor to the end of the paste
-`gP` pastes before the cursor and moves the cursor to the end of the paste
In insert mode type `Ctrl-r` to paste and then type a register, normally `"`, this will paste from that register where the cursor is and move the cursor to after the paste.
