### On occupational short-range ordering in crystal

When multiple atomic species (including vacancies) coexist on the same crystallographic site, it immediately brings up a question - say, we have species A and B sharing the same site, then do we have clustering of A and B in separate domains, or do we have A and B preferring to stay together, or do we have random distribution of A and B? This is usually what we mean by short-range order (SRO) and what we have mentioned here is specifically the occupational SRO (one can find introduction about more types of SRO in Chapter-10 in Ref. [1]). Detailed theoretical description about SRO can be found in Refs. [1-3] - the early paper by J. M. Cowley [2] gives the definition of SRO for binary systems; the one by D.De Fontaine [3] extends the definition to multi-component system (to give the so-called pairwise multi-component SRO, i. e. PM-SRO); the book by R. B. Neder and T. Proffen presents in details practical implementation and calculation of SRO, in DISCUS framework. Here I am not going to

### Sublime Text 3 - Key binding configuration issue

For many packages installed in Sublime Text 3, either we can configure the key bindings for executing available commands by going to 'Preferences' →'Key Bindings', or we can go to the package specific key binding setting section. However, sometimes, we don't have a dedicated key binding setting section for some of the installed package, e. g. 'Google Search' package. In this case, it becomes a headache to set the key binding since we don't even know what commands are actually available there. To get an idea about what commands are available for such types of packages, we can go to '%APPDATA%\Sublime Text 3\Installed Packages' directory (taking Windows OS as an example) and find the package file, e. g. 'Google Search.sublime-package'. This file is just a zip file which contains all the necessary stuff of the installed package. Therefore, we can copy it to somewhere and change the file name extension to '.zip' and open the package w
