Tips and Tricks

Basics#

Mouse Support#

Enabling mouse support comes in handy when using an iPad without a keyboard as you can freely change panes in tmux or scroll throughout your apps with your fingers, few popular ones include:

TMUX:

set -g mouse on

VIM:

set mouse=a

EMACS:

(xterm-mouse-mode 1)

Serving development website over HTTPS#

Fastest way of using HTTPS on remote machines for development is with the Caddy web server. First install it as an executable, but not service, then create Caddyfile with reverse_proxy line like this:

example.com {  reverse_proxy 127.0.0.1:1313}

Or start Caddy directly in reverse-proxy mode from CLI:

sudo caddy reverse-proxy --from example.com --to 0.0.0.0:1313

Starting TMUX/Screen on session start#

Adding startup commands is as easy as going to Host settings, scrolling to bottom and inserting command we want to use:

tmux a -t session_namescreen -rd session_name

Or anything other that we want to run when starting a new session. It also can be run from Blink command line:

mosh host -- tmux a -t session_namemosh host -- screen -rd session_name

SSH port forwarding from remote machine to iPad#

Forwards connections from a port on a local system to a port on a remote host:

ssh -L 3000:localhost:3000 ssh-host

Blink: Using screen corners#

Taping three fingers on the screen will bring a Blink menu in which you can set the Cover, Fill, and Fit setting, adapting Blink to different screens and devices.

  • Cover: Edge to Edge
  • Fill: Space at the Top and Bottom
  • Fit: 5 points on all sides

External Display: Apple TV#

You can use Apple TV as a second monitor, just start screen share on Apple TV and Blink will use it as second monitor, not just mirroring. This is really cool if you are doing a presentation, or if you are on the couch with your phone and want to have a bigger display!

External Display: Split View#

For the external display to work, Blink needs to be an active window on the iPad. A very cool way to do this is to use Split View on the iPad, giving Blink ½ or ¼ of the screen, while the rest can be taken by Safari or anything else you need!

Display: What is Blink Window?#

From iPad OS 13, we have multiple windows support inside Blink, and each window can have infinite tabs. Blink Shell Windows

You can also move windows between iPad and External Display with Shift + CMD + O or change focus to it using CMD + O.

Keyboard: Separate Keys#

By switching off the "Same for both sides" option in Config > Keyboard > ⌥ Option you can use one key as a Meta and the second as a normal ⌥ Option/Alt. It's particularly helpful for users that use languages containing diacritic letters.

Advanced#

Inline Images#

Blink supports displaying images over SSH when using iTerm2 imgact. Put it in local .bin folder ($HOME/.bin or any other in your %PATH) and use it as this:

imgcat image.png

NOTE: This does not work in terminal multiplexers (TMUX, GNU Screen) or inside Mosh.

Alternative that works inside every environment, but needs Rust installed is VIU. Install it using Cargo:

cargo install viu

And use:

viu image.png/animation.gif

TMUX: Copy/Paste using OSC52#

Enabling copy/paste between tmux and iOS needs SSH or Blink Mosh Server.

set -g set-clipboard onset -ag terminal-overrides "vte*:XT:Ms=\\E]52;c;%p2%s\\7,xterm*:XT:Ms=\\E]52;c;%p2%s\\7"

VIM users can set this to have similar experience to VIM:

bind-key -T copy-mode-vi v send-keys -X begin-selectionbind-key -T copy-mode-vi y send-keys -X copy-selectionbind-key -T copy-mode-vi r send-keys -X rectangle-toggle

How to enable OSC52 support in Mosh?#

You need to build Mosh from source with this patch: Support additional OSC 52 clipboard types #1104

Editors#

VIM: Copy/Paste between remote machine and iOS#

To enable copy/paste you'll need to install ojroques/vim-oscyank and add this line to .vimrc:

autocmd TextYankPost * if v:event.operator is 'y' && v:event.regname is '' | OSCYankReg " | endif"

And enable this setting:

set clipboard& clipboard^=unnamed,unnamedplus

VIM: Exit insert mode without ESC key#

Change CapsLock in Blink Settings to Control and press Ctrl(CapsLock) + [ to exit insert mode on iPad keyboards without ESC key.

Emacs: Copy/Paste using OSC52#

To enable copy/paste on Emacs you need to install osc52.el and add this to your config:

(require 'osc52)(osc52-set-cut-function)')

Emacs: Custom Presses#

Using the Config > Keyboard > Custom Presses settings you can add new shortcuts. For instance, sending ctrl-space when hitting ctrl-space, as opposed to bringing up iPadOS's emoji menu. Now Emacs cut & paste doesn't need to rely on ALT - x set-mark-command.

Emacs: Change ALT to Meta#

Change "Prss and send" to None and "As modifier" to ESC option in Config > Keyboard > ⌥ Option so you can use it as Meta. From now on ⌥ Option/Alt - x will work as Meta - x.
