Move to prev/next glyph: Page Up and Page Down or Fn + left/right arrow keys
All keyboard shortcuts for commands in the menu can be reassigned the system preferences. Everything that has no menu entry is not changeable in the moment. But try not to recreate the shortcut from FLS if you haven’t a very important reason.
Now, I have changed the order of the glyphs to how I like it, but when I use Fn + left/right arrow keys then it just goes to wherever glyphs figures is the next glyph and doesn’t follow my order. For example it goes from a to a.acute not to a.alt.
Generating glyphs doesn’t work for me. It doesn’t do a thing. Only by pushing shift+cmd+G again and then esc aborts it and lets me get out of it.
Setting anchors: Is there a way to define where (on a horizontal line) they are set automatically, or do I have to set them then manually? Can I differentiate where top and bottom anchors are set?
How did you change the order? If you use a list filter, only the display order is changed, not the actual order in the font. To do so, you have to add a "glyphOrder" custom parameter to the font. But if you use Fn+Shift+left/right arrow keys, the display order should be used to move to the next/previous glyph.
What do you mean with "Generating Glyphs". Do you mean Font > Add Glyphs... ?
If you use Layer > Set Anchors, the bottom anchors are set on the baseline and top anchor on the x-height/cap-height. If you use the context menu, they are set at the position of the mouse click.
Add a regular guide line, right click the selection knob and choose "Make global Guideline".
