\\[*][extra space]
The \\ command tells LaTeX to start a new line. It has an optional argument, extra-space, that specifies how much extra vertical space is to be inserted before the next line. This can be a negative amount.
The \\* command is the same as the ordinary \\ command except that it tells LaTeX not to start a new page after the line.
\\[*][zvlastni mezera]
Prikaz \\ v LaTeXu, zpusobi prechod sazeni na novy radek. Ma volitelny argument (zvlastni mezeru), ktery urcuje kolik mista navic (ve vertikalnim smeru) se ma vlozit pred novy radek. Tato hodnota muze byt i zaporna.
Prikaz \\* ma stejny vyznam jako \\, ale zakazuje LaTeXu udelat strankovy zlom po tomto radku.
