Because of powder flow limitations in this step, a slow-speed process that works well may not work at all when rates are increased. Weight variations in the final dosage form can occur when the flowability of the final formulation limits the separation of small quantities of powder from the larger mass of powder. In pharmaceutical processing, insufficient flow can lead to product quality failures, due to large weight or dosage variations. It determines for example whether bins can be used or hand scooping is required, to what extend product is scraped at the beginning or end of a run, and the allowable production rate of products. Flow is also relevant for manufacturing efficiency for batch processes. In a continuous manufacturing line for example, consistent and continuous flow through the system is a critical requirement for finished product quality. Often understanding powder behavior is crucial to properly design the process and equipment. Powders are used in many industries and in a broad range of processes and applications. This study also revealed that obtained insights on rheological behavior can be used to optimize agitator settings in a tableting machine. The presence of fines between larger particles turned out to reduce the rheological index, which the authors explain by improved particle separation at more dynamic flow fields. Particle size distribution was identified as a main contributing factor to the rheological behavior of powders. A new parameter for rheological behavior was introduced, which is a measure for the change in dynamic cohesive index upon changes in flow field. In the current study, the rheological behavior was investigated for a wide range of excipients with a wide range of material properties. One of the challenges in mimicking the die filling process is the impact of rheological powder behavior as a result of differences in flow field in the feeding frame. Many flow characterization techniques are present, but so far only a few have shown to mimic the die filling process successfully. With supertab's longest match enhancement disabled, typing B while still in the completion mode will end up completing 'FooBarBaz' or 'FooBarFoo' depending your settings, instead of the next longest common match of 'FooBar'.With the emergence of quality by design in the pharmaceutical industry, it becomes imperative to gain a deeper mechanistic understanding of factors impacting the flow of a formulation into tableting dies. Vim's builtin longest support will complete the longest common text 'Foo' and offer 'FooBarFoo', 'FooBar', 'Foo', and 'FooBarBaz' as possible completions. The documentation continues with this example where your buffer has the following contents: FooBarFoo Supertab will provide an enhanced longest match support where typing one or more letters and hitting tab again while in a completion mode will complete the longest common match using the new text in the buffer. then according to :h g:SuperTabLongestEnhanced.

If you enable it with :let g:SuperTabLongestEnhanced = 1 In the Supertab docs there's a global configuration variable that seems related: g:SuperTabLongestEnhanced. I don't use Supertab but that sounds similar to Vim's 'wildmode' setting 'longest'. Here, I expect it to again complete to the longest word FooBar and show valid suggestions. Now I type FooB and it starts scrolling and autocompletes to one of the suggestions. With set completeopt=longest,menu,noselect, it autocompletes to Foo and show the menu with the remaining suggestions. The behaviour I expect is to show a menu only for showing suggestions, no scrolling. Another tab starts scrolling through the menu. The one below allows it for just the first tab. The behaviour would be similar to: set completeopt=longestīut with a menu only for previewing the suggestions.

You keep typing and pressing tab until you get the required word.

In the end, the behaviour would be same as how bash works. Is it possible to prevent replacing the text under the cursor, maybe my preventing scrolling even if I press tab multiple times. When I press tab for autocompletion (with the supertab plugin, but its applicable with vim's autocomplete feature as well), the selection scrolls from the bottom-most selection towards top with the selection text being replaced under the cursor.
