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>}
