Scale Stroke & Effects Hotkey
Shortcut key and checkbox on UI to scale strokes with objects, etc. so you can choose if you want them to size or not, without having to uncheck the option box in Preferences.

A more narrow but related request, about being able to toggle it on the fly, while already scaling something:

i just noticed that these toggles are in the properties window when nothing is selected, which will speed me up a little. so keyboard shortcut designation is all i'm looking for now

Its possible that i just don't know how to do this because it seems pretty obvious. i want to be able to toggle (within the preferences/general section) the scale corners, and scale stroke width options because i use these options on, as much as i use them off. Currently, the workflow of cmd K to open preferences and then locate and toggle over and over feels like its using too much of my time.
I would like to assign an unused quick key, or have the option to pin the toggle to the control bar or the properties window -

線幅を拡大縮小にショートカットが欲しい。又は、キーボードショートカットで作成できるようにして欲しい。
デザインの作業で、同じドキュメント内でも線幅を拡大縮小するかはオブジェクトによって違い、かなり頻繁に、そしてスピーディな作業の中で必要になります。
そのため環境設定か、拡大縮小ツールをダブルクリックし、チェックボックスにチェックを入れたり外したり、という作業が非常に煩わしいです。
