    ### Search

    Usual `/` and `?`, but `<spc> sc` to clear any persistent highlighting.

    `<n>G` to jump to line n. Eg `121G`

    ### Quickly change font size

    `Ctrl-x Ctrl-+` and `Ctrl-x Ctrl--`

    or

    `<spc> z x` and then repeatedly as required use `=` (reset), `+` (increase), and `-` (decrease). Any other key to leave this mode.



    ### Multiple cursors

    - https://github.com/tsdh/iedit
    - https://github.com/syl20bnr/evil-iedit-state


    E.g., put our cursor on cat below, do do

    - space se (switches to iedit mode, red)
    - `<spc> s e` (switches to iedit mode, red)
    - L (restrict to current line, excluding the word cat <- here)
    - S dog ESC ESC (replace all)
    - `S` (substitute) dog ESC ESC (should replace cats with dogs)

    ```The cat sat on the cat by the cat```

    ### Block mode

    E.g., go to the `<` in `<- f` below. Press `Ctrl-v`, then down cursor to select the next line.
    Go into insert mode by pressing `I`, tap space then `ESC` You have aligned the generators.

    for {
    a <- f
    b <- g
    why <- h
