The vast majority of GUI based programs use an object-action paradigm,  one select the object e.g. a component or wire) then decides what to do with it (e.g. move, rotate, copy).

I use LTspice HOWEVER...

The GUI is trash because the menu buttons don't scale with screen resolution.  With a 3000x2000 screen even scaled to 300%, the buttons are still virtually invisible.  Buttons like 'Move' are VERY hard to find. There's little contrast and the button is less than 1/8" even on a 27" monitor.  It is almost impossible to use on my 13" Surface Book.

With a 1920x1080 display the program is fine.

Nobody else seems to have this problem.  Probably because they don't size objects in terms of pixels.

So, I use LTspice but only if I am desperate!  It's a great tool but not on my main system. When I'm really desparate, I run it on another machine.

"Move" button, what Move button? Move is F8, obviously!  There's a button?
F6 to copy, F5 to delete. F7 to lift and move (separate from connecting wires when moving). F9 to undo. F3 to draw wires. Basic components all have shortcuts too, R, L, C, G, etc.  Control-R to rotate and Ctl-E to flip.  I would find it very annoying to have to move the cursor away from where I am working, just to click some silly button.

So would I, that's why I put the tool bar at the bottom, you can move it almost anywhere, even on top of the schematic.

I work with the schematic in the middle of the screen so whether the toolbar is at the top or bottom makes no difference to how far I have to move the mouse.

I think the keyboard shortcuts could be easier to discover. They should be on the pop-up when the cursor is placed near the tool bar.

Yes, they're listed under 'Edit', and others.

But the edit menu isn't used regularly by most users for them to discover them, because most tools can be found on the toolbar.
