termoption

The set termoption command allows you to change the behaviour of the current terminal without requiring a new set terminal command. Only one option can be changed per command, and only a small number of options can be changed this way. Currently the only options accepted are

     set termoption {no}enhanced
     set termoption font "<fontname>{,<fontsize>}"
     set termoption fontscale <scale>
     set termoption {linewidth <lw>}{lw <lw>} {dashlength <dl>}{dl <dl>}
     set termoption {pointscale <scale>} {ps <scale>}
