Too many… or too few? >:D
iMo:
Simply place the probe at the wire such it shows "voltage". Then click at that voltage value and you will get a window with all the voltages and currents in your circuit. Do select a current flowing through that wire. It will show you the current then. You may have current as well as voltage probe set at a wire.. See below..

In the past I've added a 1uohm resistor into a circuit to measure current where it was not otherwise possible to measure current through a specific net. LTSpice does not allow you to use a zero ohm resistor but a micro-ohm is a close approximation to one.

Hi, if you need to do this, use a 0V voltage source as the sensing element.

Pressing Alt whilst the mouse cursor is over the net works for me. Under WINE I need to hold both Alt keys, or the Windows+Alt. Failing that, manually enter the components in, for example if it's three resistors I(R1)+I(R2)+I(R3).
