    # - --RAW-CONTROL-CHARS (R) = output raw control characters
    # - --chop-long-lines (S) = chop long lines instead of wrapping
    # - --incsearch = start searching immediately as you type `/<search-term>`
    # - --no-init (X) = Don't use termcap init/deinit strings (hence, `less` output is visible on the terminal even after exiting)

    # - --quit-on-intr (K) = exit on ctrl+c
    # - --shift=.n = left/right arrow-keys scroll by `n` screen widths
    # - --use-color = enable color instead of just monochrome (highlights search matches)
