Low-vision configuration for terminal applications

I usually find that Unix terminal applications work reasonably well in large print as long as the terminal itself can. However, increasting the print size usually means that fewer rows and columns are available, and some applications don't work very well on terminals with fewer than normal rows and columns. This can sometimes be fixed by configuring the application. Here are some of my dot-files for this and related fixes:

.muttrc is used to configure the terminal-based email client mutt. This dot file works better if you add .message-formatter (requires Python), and check the comments at the start of the .muttrc for what to do if messages are not displayed on your system.
.jedrc and .nanorc are used to configure the jed and nano editors.
.lynx.cfg and .lynxrc are used to configure the terminal-based Web browser lynx. This works only if you put export LYNX_CFG=$HOME/.lynx.cfg in your .bash_profile/.bashrc.

For top, try pressing f and turn off columns you don't really need (try h, i, q, t, m, and perhaps turn off e and turn on d on single-user systems), press c to toggle extended commandline and press W to write to .toprc.

Linux console

On modern Linux distributions the console font size is quite small. You might be able to go some way toward enlarging it by using this .console-setup and putting setupcon in your .bash_profile, or if you don't have setupcon then try setfont /path/to/TerminusBold32x16.psf.gz. For fonts larger than that, use X11.
