It would be great if Customize Toolbar would permit adding any function that is available in the menus. In my case, I wanted a button to open the Windows Character Map.
The ability to put a shell command in a toolbar button would also be powerful.
Thank you for a fantastic piece of software! I’m really enjoying myself.
We do not have nearly the budget to create the hundreds of icons that would be required to make that possible, to the standards of quality we are comfortable with. We critique each icon individually and sometimes go over several revisions with the designer, that may seem excessive but that is just how we do. 
This is especially true considering that going forward, we have to design two entirely different sets of icons for low and high-res monitors.
Artisan icons! Hand-crafted! Brewed with love, polished by unicorn hair!
Just another service brought to you by L&L.
And never over-hopped!
Note: No unicorns were harmed in the making of this thread. The unicorn hair used to polish icons is collected daily from hand brushes after grooming. All unicorns are free-range, have a diet of fresh rainbow juice, and are allowed to age naturally. Literature and Latte has been independently validated as unicorn friendly.

Why doesn’t that surprise me 
tch! tch!
Move over Blade Runner.
How does the alternative work? Warped space-time?
I’ve added a simple AutoHotKey toolbar overlay, for those who are comfortable augmenting their Scriv capabilities with AHK button bars and macros in a minimalist aesthetic.
Toolbar overlay, with “Character Map” and “Reveal in Binder”
Rgds – Jerome
Denying the capability on that basis was a poor call, in my view. Text buttons are a routine option in customized toolbars, as in Office prior to the Ribbon. I have “Reveal in Binder” and “Lock in Place” on a simulated toolbar via AutoHotKey, and deploy these buried commands much more freely as a result. With appreciation for Scrivener’s visual appeal, and for the need to focus on its most useful icons, I’d recall the miracle of the alphabet. We’re people of the word, not constrained to those tasks we can easily portray in hieroglyphs.
Hope you’ll reconsider – Jerome
It’s my personal opinion, but I think a mixture of text buttons and icons looks rather bad. I know that’s how Microsoft does it with their ribbon design, but everything about the ribbon makes me want to cry, from a design standpoint as well as usage. I have nothing against text buttons on a toolbar, to be clear, but only if that is the mode of operation: as in no icons at all, just text. I kind of like that look, and when I do find myself in a program that forces toolbars for normal usage, if it has the option for text only, I take it.
Technically not necessary, as explained via Fleinstein’s unicorn exception theorem. Unfortunately it’s difficult to validate empirically without placing unicorns in a particle accelerator and, to date, no university will give ethics approval. Despite this, I wouldn’t put it past unscrupulous unicorn farmers to warp space time to increase profits.

And how does unicorn differ from other species or breeds of corn? 
(I must admit being somewhat at loss about how corn is connected to custom iced toolbars being more flexible…). 
{… and a toolbar is where you get tools, and possibly a drink?} 
It’s uniquecorn
and:
The sense of humour, of those tooled-up, alcohol enhanced customers, usually tends t’wards being ‘corny’,
merriam-webster.com/thesaurus/corny and their appreciation of all thing pertaining to propriety is at best elastic.
“Aaahhh… Now I get it” he said, and bent the customized toolbar so it’d fit in the corn’er.
Well, you do appear to be getting the picture. [size=50]not before time[/size]
First: NO do NOT want to create a shortcut for this. Too many keyboard commands already. mac does not have a good way to show ‘what are all of the currently active keyboard commands while I’m in this application.
I often cut and paste from other programs where a blank line is used to indicate a new paragraph. Markdown and html both tend to work like this.
Paste into Scrivener, and then I have to go Edit → Text Tidy → Remove blank lines
I would like to be able to configure this as a button on the tool bar.
For seeing all the keyboard commands available, I use KeyCue. Pressing and holding the Cmd (⌘) key on my Mac will show all the active keyboard shortcuts in the program I’m using, as well as the defaults for the System overall.
Since you don’t want a keyboard shortcut, I’m not sure there’s a good way to do what you’re asking at present. I’d point to BetterTouchTool or Keyboard Maestro, but those are again the keyboard shortcuts you’d rather avoid.
(Edited to add KeyCue link.)
I get that there’s likely no easy way to provide this. I also realize that the ScrivenerVerse Is Not A Democracy. Even if it were, folks who want Yet More Keyboard Shortcuts (YMKS) are numerous and vocal, and those who prefer mouse use and toolbar buttons (like myself and the OP) seem less numerous and/or less vocal, so we’d lose the election anyway.
Nonetheless, folks who like more keyboard shortcuts have both OS-based options (at least on Mac) and third-party utilities available. Folks who prefer mouse-based, graphics-oriented interfaces have far fewer options. Please don’t forget us. A wider selection of toolbar buttons would be wonderful the next time y’all are messing around with the interface. Even a “customizable” blank button would help.
I was just about to post the same recommendation. To those who want to give it a go: GitHub - Anze/KeyCluCask: Simple and handy overview of applications shortcuts · GitHub of you rather download DMG: Release v0.31 · Anze/KeyCluCask · GitHub
It does lot more than just show the available commands:
A few of the things you can do with KeyClu:
Adjust view to your liking
Personalize appearance to system, light and dark
Bookmark shortcuts
Hide known shortcuts
Collapsible groups of shorcuts
Export App’s shortcuts to markdown file
Display macOS hotkeys
Display skhd hotkeys
Display own shortcuts
