BTW, I had to change the font as in the default one, the lower-case L and the numeral one look exactly the same. Who would pick such a font for a programming editor?!
They do in the default size yes. I think this is one of the reasons people don't have variables with names like var1 and var2, normally going for var and then var2
I agree that the font setup is awful - I wanted to make my text slightly smaller but there was no chance as it looked so bad.
