That new feature of the Surface app only seems to be available for Surface Pro 4/SP4 pen. SP3 and S3 owners do not see this new feature.
From https://www.thurrott.com/mobile/microsoft-surface/63102/microsoft-now-offers-full-surface-pen-button-customization
Guzzler3 posted these instructions over at WindowsCentral. He said it works for the SP3 pen, too, and I would think it would work with the Surface 3, as well. I haven't tried it yet, myself, need to wait until I get home:
First, you have un-pair your pen in the Bluetooth settings.
Then you have to uninstall the pen drivers (Device Manager: Right click: Uninstall and remove files the following entries: "HID-compliant pen" & "Surface Pen Settings").
Then you have to download the Surface Pro 4 drivers (https://www.microsoft.com/en-u... )
SurfacePro4_Win10_151203_0.zip.
Extract the ZIP file, navigate down to \Drivers\Pen and install the following:
SurfacePen
SurfacePenPairing
SurfacePenSettingsDriver
By going into each directory and right clicking the .INF file and select "Install"
Restart your SP3 Then re-pair your pen in Settings, Devices, Bluetooth.
Then you can open the Surface App and you will see the additional pen settings.

先继续用自己的方法顺便等微软更新吧

确定用Pro4的笔驱动没有副作用？

太棒了！亲测可用！！

安装好了, 可惜只比原来多了个在OneNote里面的双击截屏, 那个笔按键定义界面在哪里弄出来的啊? 找不到

surface3安装失败，按照教程安装完成后根本找不到surface app

成功，但是........我要的双击cortana就是不行其他全部正常

请问笔下面还有两个按钮是干嘛的？

晕，说一下，改了驱动之后，如果运气不好，经常蓝屏，错误代码是driver power fail，

学习了，暂时还是不更了

大神厉害啊，终于可以打开桌面版one note了，感谢楼主and翻译
