Is there a way to use \ref like \href

Question

Question is as in the title.

Using \href, we will be able to give a "clickable" link along with text. Can we do the same with \ref. Suppose I want to refer an equation with label \label{equation:123}, I usually write Equation \ref{equation:123}. Is there a way to write something like \ref[Equation]{equation:123} or \ref{Equation}{equation:123} similar to \href{00}{00}?

Unrelated, \rm has been obsolete since 1993. I'd use \DeclareMathOperator\Spec{Spec} instead — daleif, May 18 '21 at 14:44
hyperref lets you do \autoref{qwerty}, but the cleverref package may be better, See e.g. https://tex.stackexchange.com/questions/39349/automatically-inserting-section-subsection-etc — Torbjørn T., May 18 '21 at 14:49
One important note. The package name is cleveref with one r, not two (just finished the cross referencing section of my book last week). — Don Hosek, May 18 '21 at 14:56
it is unclear which printed text you want and where it should lead to. And your example is quite useless as it doesn't have any reference in it. — Ulrike Fischer, May 18 '21 at 15:00
@daleif I did not know about \rm being obsolete. I will use \Declare** from now — Praphulla Koushik, May 18 '21 at 15:02
@UlrikeFischer I already mentioned in the question. I want Equation (equation number) when I write \ref{123} and I do not want to write Equation \ref{123} everytime — Praphulla Koushik, May 18 '21 at 15:03
but this is not what \href does. \href is for free text. So why do you ask for something similar to \href? — Ulrike Fischer, May 18 '21 at 15:08

The solution to your problem is to use the cleveref pacakge (note that it's just one r in the name). You will want to load it with the nameinlink option in conjunction with hyperref:

\usepackage{hyperref}
\usepackage[nameinlink]{cleveref}

You can then write \cref{equation:123} in place of equation~\ref{equation:123}. Use \Cref for capitalization. If cleveref inserts abbreviations where you'd prefer it did not, you can add the option noabbrev to prevent abbreviations.

Further information can be had by typing texdoc cleveref at a command line.

Thank you. As of now I do not see any problem :D This is exactly what I want. – Praphulla Koushik May 18 '21 at 15:11
Can this be used to refer multiple equations at a time? something similar to \cite{,,**}? – Praphulla Koushik May 18 '21 at 15:15

Yes, you can write, e.g., \cref{ref1,ref2,ref3}. Or to refer to a range write \crefrange{ref1}{ref2}. See the documentation for lots more information. – Don Hosek May 18 '21 at 15:19
This is very nice.. Thank you so much :) – Praphulla Koushik May 18 '21 at 15:49
one last question.. for some diagrams I am using \begin{equation} \label{diagram} \end{equation}.. So, if I use \cref{diagram}, I will get Equation (diagram number) and not Diagram (diagram number).. Is there an easy answer to this or shall I ask it as a separate question? – Praphulla Koushik May 18 '21 at 16:12
That's a separate question. – Don Hosek May 18 '21 at 16:32

If you don't want to add cleveref to an already bloated preamble...

\documentclass[12pt,reqno,a4paper]{amsart}
\usepackage{hyperref}
\newcommand{\myref}[2]% #1=added text, #2=label name
  {\hyperlink{\getrefbykeydefault{#2}{anchor}{Doc-Start}}{#1~\ref*{#2}}}
\begin{document}
\begin{equation}\label{eq:1}
  x=a
\end{equation}
\myref{Equation}{eq:1}
\end{document}
