| " If you want to test this, save it somewhere, open in vim, `:so %`. | |
| " Slowly type <leader>g andand g-commands should happen in the other buffer. | |
| " In the demo webm above, I just slowly typed `<leader>gJ` | |
| " I only added descriptions for a few commands but others should work | |
| " Needs massive re-working to actually be maintainable | |
| " WHY: | |
| " Vim is an amazing tool, but one of it's few weaknesses is discoverability. | |
| " While it's great to have a tool that you can continually learn new things about, | |
| " learning those things would ideally happen sooner than later. Spacemacs ships with "which-key" |
