Inside a Chromium application the flag settles this on its own - with autoscroll on, Blink stops pasting the primary selection. Everywhere else on the desktop middle click goes on pasting, which is the thing this whole program exists to get away from. KWin has a switch for it, on Wayland, where the paste is a protocol the compositor either offers or does not: EnablePrimarySelection in kwinrc. Written with kwriteconfig, the way System Settings would, because kwinrc has a cascade behind it. What the key said before goes in the ledger, so disable puts it back - and a key that already said false is left alone and not recorded, so a paste the user switched off themselves is never switched back on. X11 has no such switch and nothing is written there.

# middleclick-autoscroll
|
|
|
|
middleclick-autoscroll (what a great name, wow) is a CLI for linux that enables autoscroll in every application that supports it.
|
|
Works with browsers, electron apps like discord and spotify, steam, and anything else that runs on chromium.
|
|
|
|
This tool looks at which of your apps run chromium under the hood and applies the necessary steps to get autoscrolling working (often just a feature flag). One install, one command and autoscroll _✨just works✨_ (like on windows).
|
|
|
|
## How to use
|
|
|
|
Just run `middleclick-autoscroll`. This will open the configuration TUI that looks like this:
|
|
|
|
```
|
|
Middle-Click Autoscroll

|
|
|
Autoscroll ON

Normally you just need to press `[1]` and the magic is done.
|
|
Pressing `[3]` lets you see every app that was found and toggle each one individually.

|
|
curl -fsSL https://felitendo.github.io/middleclick-autoscroll/KEY.gpg \

sudo zypper addrepo --gpgcheck --refresh \
|

https://felitendo.github.io/middleclick-autoscroll/rpm middleclick-autoscroll
|
|
sudo zypper install middleclick-autoscroll
|
|
```
|
|
|
|
## How it works
|
|
|
|
Blink (the engine in Chromium, Electron, and CEF) already has autoscroll, but
|
|
it's off on Linux by default because middle click normally pastes the clipboard (??).
|
|
This flag turns it on:
|
|
|
|
--enable-blink-features=MiddleClickAutoscroll
|
|
|
|
But doing that for every app is kinda bothersome and it also might break with updates.
|
|
That's why I created this small tool to automate that.
|
|
|
|
Browsers get the same thing but this time without "blink":
|
|
|
|
--enable-features=MiddleClickAutoscroll
|
|
|
|
But both do the same ¯\_(ツ)_/¯
|
|
|
|
New apps are picked up by a systemd path unit that watches the
|
|
relevant directories. If you hate systemd; `middleclick-autoscroll apply` does the
|
|
same thing manually.
|
|
|
|

## Building from source
|
|
|
|
```bash
|
|
make
|
|
sudo make install
|
|
```
|
|
|
|
Optionally needs `msgfmt` (gettext) for translations and `scdoc` for the man
|
