Hello forum!
I’m really loving Dorico in my day to day work life as a musican and music teacher, but i really miss being able to do quick system breaks in write mode. When doing fast transskription work it would be very useful. A fast way to do system breaks, as you type, is the only feature i miss from sibelius.
Is there a way to do that, or do i just hope that the function comes in a later version?
Kind regards
No, this is layout specific, so you have to do it in Engrave Mode.
But: there are shortcuts to change Mode: ctrl/cmd-1 … ctrl/cmd-5
So if you really want to do system breaks while writing:
For me that was fast enough, if I needed it. But most of the time I would just write everything sequentially, and then ctrl/cmd-3 and do the system breaks.
EDIT: corrected Layout Mode to Engrave Mode
You can actually build a macro to do the above, and then assign that to a key command for even faster access!
Record the macro of adding a system break in engrave mode as meixner just described.
Or create a plain text file with the following:
local app=DoApp.DoApp()
app:doCommand([[Edit.CreateSystemBreak]])
save as SystemBreak.lua in your Script Plug-Ins folder (search for where this is located on your system). Restart Dorico. Now it will appear under the Script menu command to run as a macro.
You can then assign this to a key command using an external application or if you’re on a mac easily in the keyboard system prefs.
This! of course 
You can also copy and paste System/Frame Breaks in Write mode.
Thank you all for The detailed responses! I will look into it. What an amazing forum this is.
I still wish there was an easier way to do it with a single shortcut without the deep dive, but oh well, maybe in another update.
Stream deck can do it, but only you decide if it’s worth getting one for this function only initially…
Obviously, it can do a ton more on top of this!

Dorico gently tries to convince you that, when in Write Mode, you completely concentrate on pure musical input. Don’t even think of the layout, even if so far you have been used to do so.
Switching to Engrave Mode at a later stage your attention can be turned away from the music itself and all awareness can be focused on the layout aspect.
This separation will in the long run reward you with better quality score output…
Sorry I don’t think that makes any sense. There are always som auto layout going on, and small adjustments done by dorico itself, which you need to not lose track of what you are doing, and for me and a lot of others, system breaks are an essential part of that same writing fase.
People have different ways of working anyways and there are infinetely different specific musical scenarios, where you need different approaches. I’m just asking for a little more flexibility.
@dylletron , if you work in Page-View, you will always be confronted with layout issues. If you do the same in Galley-View, you will be able to work much faster - as neither Dorico nor you will be busy doing any formatting.
If you can’t give up your usual routine, you could for once start up your Dorico installation in the SE version. Because SE has no Engrave Mode, it has System- and Frame-Break Shortcuts in Write Mode.
For SE, hold CTRL/CMD down while starting Dorico.
just to reinforce, there will be no layout adjustments going on, if you are in Write-Mode and Galley View.
Thanks for the tips, I will try out writing in galley view! I’ve never used that function.
Also a very good tip, I could see how that would be useful in some situations, thank you!
Writing in Page Mode actually helps me with the structure of the piece, in the sense of a better overview and such… but again, I use stream deck and can fire off System Breaks while writing.
Completely agree, and I still would very much like a customizable shortcut for system breaks in write mode.
I don’t know if this is the better way.
My experience : Whether in Finale or Sibelius, I have always operated as follows:
In short, Dorico’s various interfaces simply reproduce this type of protocol.
Of course, I don’t necessarily wait until I’ve finished the piece to do all the first three points. In a large orchestral score, I work by sections, otherwise it’s easy to forget this or that sign, this nuance and so on.
And, to round it all off, reread, reread, reread.

For the specific use case, as described in the original post, it’s definitely a must to do system breaks while transcribing. I would just like the option to integrate system breaks in that workflow easier.
I don’t believe there is one single protocol of writing that works for everyone and all material/types of tasks.
But I agree that for a lot of work, the method you described works excellent.
Our work routine structures our thinking, “moulds” our brains.
I put floor tiles onto the floor of my house, it took a few days. But it took also some weeks before to check and select a good pattern and material.
After the work was finished, I still saw patterns everywhere I looked, I checked distances of narrow joints everywhere I looked…
This just as an example…
If I worked in a software where I had a measure or one bar as a starting point, then think of structuring the bars into systems next, then populating these “frames” with notes and rests - of course my brain will adapt to this!
That’s why it feels like driving without brakes, when using Dorico for the first time. You don’t need to think of measures, time signatures or system breaks at all, while you transcribe your music, just let go… Than structure it in a following step. Luckily our brains are very flexible
it depends on your age. I’m an old man. 
I don’t agree. For me it’s much faster to have very clear structure while transcribing lead sheets
