LTspice Hot Keys
LTspice allows Hot Keys to be (re)assigned to many of its functions. Of all the possibilities, the following key plan (for the Schematic Editor window) is perhaps one of the most convenient.
Why these particular keys?
They allow the right hand to drive the mouse while the left hand stays in place to select objects and actions without the eyes ever having to leave the screen. Note that the most critical functions are assigned to the most easily reached keys (darker background) and that the editing keys are shown in three groups according to whether they are objects, actions or drawing (unshifted, ctrl-key or shft-key). Keys that are changed in function from the default assignments are depicted in color with relocated functions shown as greyed strikethrough text.

One-Step Keyboard Reconfiguration Method (via SCAD3.ini file edit)
Hot Key assignments following this same pattern can and should be applied to the Waveform Viewer, Symbol Editor and Netlist Editor windows as well. Although these may be entered manually one-by-one via the LTspice Control Panel, it is perhaps more convenient to copy these Hot Key plain text definitions and use them to replace the existing Keyboard Shortcut sections of LTspice's configuration file (the standard installation location is C:\Windows\SCAD3.ini).
Tip: If you do not have administrator rights to modify files in the Windows folder, you may start LTspice with the following command line switch in order to have it load SCAD3.ini from a folder of your choosing upon start-up (one in which you do have read/write rights):
-ini <path> Specify an .ini file to use other than %WINDIR%\scad3.ini
