I defined the N as the "drag" command so they are next to one another. Then I continued to make B the "copy" command and V to draw a wire. That puts 90% of my key action where my hand doesn't have to move. I could reach 99% if I used something nearby for delete and maybe redefined escape which I'm not sure you can do. +1 on the thicker line width, I think I'm using 3 or maybe 4 rather than 1 because printing to PDF would not show up. I haven't found a way to make plots use thicker lines though so they can be printed to readable PDFs. Turns out you can add lines and printing to the plots using drawing commands. I've used that to label printouts. You can save your plot setups .plt file extension I believe. Very handy! It saves all the signals you are viewing and the scale factors on the axes in addition to the colors. You can also define custom colors so they show up better. Many, many user tips abound. So many they are hard to learn about. Sometimes it's better to have a vanilla tool and just get the job done without all the drama of a bazillion petty details to memorize. -- Rick C. + Get 1,000 miles of free Supercharging + Tesla referral code - https://ts.la/richard11209

You have to do the copy, then you can only switch schematics one way or the command is ended. I think it's with the TAB key. Click the mouse on the tab and the command is ended. Lots of goofy little things like this to learn. What really bugs me though is the arcane details of modifying symbols and adding new models.

Then people were other than polite discussing it as if the confusion is the user's fault.

Thanks, good to know! I went from CM 6 to CM 2000 Pro. Not sure what the differences are with ‘Pro’. Never use the TraxMaker section so can’t answer your question re 3D. I have a CM puzzle which I’ll raise in a fresh post and hope you see it.

My version of LTspice does use Ctl-Z and Ctl-Y for undo/redo. I couldn't stand F9 either As for the look of components, you can create your own .ASY file and make it look like you want to, except for encrypted AD or LT parts. I much prefer the wiggly resistor look..... /\/\/\/\/\/\ .......

If you don't like the schematic editor interface, you will really hate the symbol editor interface which uses different default key bindings!!! You couldn't make this stuff up.

You don't have to take your hand off the mouse. At least under Windows, copying a part or a chunk of circuit between schematics is easy. No hotkeys, just the copy symbol on the toolbar. I think the only hotkey I use in LT is g for ground. -- John Larkin Highland Technology, Inc Science teaches us to doubt. Claude Bernard

Creating a "common personal library not part of any design" is straightforward, especially for the PCB section. I've been using my own footprints exclusively for a decade and a half.
