srcltx – Jump between DVI and TeX files

Pro­vides a \spe­cial in­ser­tion into gen­er­ated .dvi files al­low­ing one to jump from the .dvi file to the .tex source and back again (given a .dvi viewer that sup­ports this, such as Yap or xdvi ver­sion 22.38 or later). This was orig­i­nally writ­ten by Alek­sander Si­monic, the au­thor of the WinEdt shell.
