clicks in a shell pane never change its mode: the body-press exitTagEdit no longer force-drops to normal (it only restores the mode a tag edit hijacked, remembered in pane.tag_mode), and the left-release cursor pin keeps the terminal's mode (files still click into normal). New ttyclick.snap covers tty body click, tty tag round trip, insert body click.

+- implement missing acme mouse chords (you should explore pardes and acme codebase to do a survey)
+- fix crash when decreasing font size on tty
 - for the web version make LOOK on a file focus it if it's loaded as a pane on the snapshot
 - when using a command that needs a selection, if there's none of the current pane, look for selections in other panes.
-- panes can be shinked to just have the tagline visible

+- panes can be shrinked to just have the tagline visible
+- when a new pane is going to open, if the chosen parent would leave it with less than 5 rows (without counting the tagline), then choose a different one, if none is found then just choose the largest one in height on the target column
 - parse the argv so that when you run pardes with no arguments: it opens in tty mode, if you pass a file it'll open that file focused (with a terminal split on the directory pardes was opened from) and if you pass a directory it'll set pardes cwd to there 
 - the gui should have a different binary name, and non linux-x64 should have the os and tag along the name too

    L  select   a plain click also FOCUSES the pane and PINS the modal
                cursor where you click, so you can edit there next.
+               A click never changes a pane's MODE (tty stays tty).
    M  execute  run the selected text: a builtin name runs it, anything
                else is SENT to the shell the pane runs. This is how you
                run a command you typed in a text mode.
