The LTspice Keyboard Shortcut Map and Setting Custom Hot Keys. I was speaking with a former coworker, engineer, and friend of mine as I was trying to help him figure out how to do some things in LTspice that he only knew how to do in Pspice, when he said something along the lines of, "you know, the thing that bugs me the most is that there's no way to change your keyboard shortcuts in LTspice." I just create an LTspice folder, with sub-folders called my_symbols, my_ccts. Drawing a wire straight through several components is an easy way of connecting the components in series. Linear Technology provides useful and free design simulation tools as well as device models. n new schematic ! you MUST also include the new symbol with the schematic.
