Text Formatting ⇒ Defining new commands

[dearleader]

Hello,

I was wondering if someone could help me with the following problem. I am trying to define a new command \bf so that \bf{a} gives \textcolor{red}{\textbf{a}}. So far I have defined

\renewcommand{\bf}{\textbf} so that \bf{a} gives \textbf{a}.

but i don't know how to incorporate the \textcolor into this. Since I used \bf{a} extensively throughout my document already, i was hoping someone knows a way to incorporate the \textcolor into this without me having to chance \bf{a} to something else througout my document.

Thank you in advance,

Jong-il

\textbf, unlike \bf, has an argument. Thus, you should use the following syntax:

\renewcommand{\bf}[1]{\textbf{#1}}

I think you'd be better served, however, by using a new name, to avoid conflicts... pick any name you haven't used yet:

\newcommand{\mybf}[1]{\textbf{#1}}

Color is not hard. Load the xcolor package:

\usepackage{xcolor}

And then you can use:

\newcommand{\redbf}[1]{\textcolor{red}{\textbf{#1}}}

(Or use renewcommand if needed, etc.)

I'm using red, but change that to whatever, as specified in the xcolor documentation.

I don't see the problem with your having already used \bf throughout the document. Doesn't your editor have a Find and Replace command?
