How can I set up a keyboard shortcut.

Welcome LeeInMo. It's actually quite easy with AutoHotkey. You can write a simple script to paste a line of text when you press a key combo, such as Ctrl+D, etc. (just don't use keys that windows uses like Ctrl+c, tec. )

AutoHotkey Tutorial: Macro and Hotkey Creation

for instance, you can use a letter not used by windows that starts your sentence

^i::
Send I want to put this text here (Just an example, the bold area would be the text string you desire)
return

or

^l::
Send Leave the door open when you leave (Just an example, the bold area would be the text string you desire)
return

You can string several together if you have several lines of text you use often, you just have to remember what the hotkey combo is

^i::
Send Install the font
return
^l::
Send Life is a beach
return
^s::
Send Ship to customer
return
^m::
Send Modify as needed
return
^g::
Send Golfballs have dimples
^r::
Send Request more information
return
^a::
Send Always talk to your manager first
return
^U::
Send Useless information
return
^t::
Send Technicians must be present
return
^d::
Send Diagnose problems
return
^n::
Send Night time is dark
return
^b::
Send Black is slimming
return
^q::
Send Quietly slink away
^k::
Send Knead the dough
return
^j::
Send Just about anything
return


You get the idea The return creates a return for a space.
