Hi is there a way to set kerning values in GUI at once for all masters? (like shift+enter shortcut key or something like that? i take a look at site and handbook but couldn’t find it, if not predicted or implemented, hopefully could be an idea) ---

What do you mean? Do you want to set a kerning value for a single pair in all masters, or copy the complete kerning from one master to another? ---

i mean on entering the the value for kerning between two pairs or classes via GUI, an optional shortcut key to set value for all masters(like option key in menus), i know kerning values are different in many situation for different masters but (you know better than me) tiny features like that make things easier. ---

How many pairs like this are in your typeface? ---

~400 ---

And how many “regular” pairs? ---

~400 on each master, i’m trying to add whole glyphs(upper/lowercase) and punctuations. (i feel you want to point that there is not that much pairs in a good space-tuned font to consider such feature, right? it’s ok, i thought it should be or would be nice to have) ---

So you have halve the kerning different and have the same between masters? I don’t think that adding a modifier to edit the kerning in all masters will work. They are all taken for the kerning with the keyboard. So I think syncing it afterwards is a better option. Either by a script that copies the kerning for the current pair to all masters or edit one master and then copy all the kerning pairs to the other masters. That depends if it is clearly defined what pairs need to be synced. e.g. all pairs with certain glyphs. Why are so many pairs that do need the same kerning? Are those glyphs the same? Can you explain a bit more what and why are you doing this? ---

i have a 300 and a 700 master on weight axis(display font) with almost same side bearing for glyphs on both masters(none-intentional practice, looking good enough), so kernings are the same. i go back and forth between masters to set same kerning values and comes in mind it should exist sth. i have no problem with that at all. thank you. ---

I had a similar question and was wondering what might be the best way to go about it. While it would be nice to set up a series of kerning string in edit view for select masters, and then kern one and see how that same value works for the others…I fear that if there was a modifier key for this that it might lead to some accidental clicking (because it’s already difficult enough to remember all the existing spacing/kerning shortcuts) and cause unintentional changes to other masters. One idea is to use [Kern-A-Lytics](https://github.com/schriftgestalt/kernalytics-rf-ext). There is an Equalize Pairs button that will _Set all pairs to be the same value as the currently selected UFO_ I forget if it is possible but after you equalize, you might be able to select the masters you want and click the increase +/- 10 button. ---

If all pairs are the same, you can use the “Link Metrics With First Master” custom parameter on the second master. But that will link everything. ---

To have both single and all pairs in sync and avoid accidental shortcut presses, it would be nice to use masters in formulas (why not both kerning and metrics): `=Regular` or `==Regular` or even `=Regular*0.2`. ---

Until the setting kerning with formulas dream comes true… Any chance someone has a snippet for copying all kerning pairs from a select master to another (set of) master(s)? ---

Cmd-A, Cmd-C, Cmd-V works well for me. ---

It is supposed to be like this: ```auto sourceMaster = Font.masters[0] targetMasters = [Font.masters[1], Font.masters[2]] sourceKerning = Font.kerning[sourceMaster.id] for targetMaster in targetMasters: targetKerning = sourceKerning.deepMutableCopy() Font.kerning[targetMaster.id] = targetKerning ``` But there was a small problem in the wrapper. Will work in the next version. [Next page](https://forum.glyphsapp.com/t/is-there-a-way-to-set-kerning-value-for-all-masters-at-once-via-gui/24681.md?page=2)
