The latexsym and amsfonts packages contain many more. This first figure is composed of 2 chains: the first 1->2->3 and the The \vec command uses \mathchar"017E as the arrow, while \overrightarrow uses \mathchar"3221. This ensures that the right arrow symbol is properly formatted TikZ and PGF Manual TikZ. You can use the \rightarrow command for both text and mathematical expressions. 2. Writing basic equations in LaTeX is straightforward, for example: However, $\xrightarrow{dim}$ puts the arrow in the centre (as one would have for a map) which makes the dim small and doesn't look good. 1 Arrows ¶ These are the arrows that come with standard LaTeX. . 1.
