POIs there a way to emulate ReSharper's "extend selection" feature in Vim?

    <p>ReSharper has a nice feature called "extend selection": by pressing <code>CTRL+W</code> (I think this is the default) repeatedly, you select more and more from your current caret location. First it's a word, then more and more words, a line, inner then outer block of lines (for example an if-block), then a function, etc...</p> <p>Basically, by pressing the key combination repeatedly, you can end up selecting the entire file. I'm sure at least some of you will be familiar with it.</p> <p>I have just started learning all the intricacies of vim and I don't have enough experience to see how something like this could be implemented in Vim (although I assume it's possible). So my question is meant for Vim gurus out there: can this be done and how?</p> <p><strong>Update:</strong> a bit of a background story. I've been talking to my ex-boss about all the benefits of Vim, and he thinks it's all great. His only question/problem was: <em>does it have "extend selection"?</em> My question so far has been <em>no</em>. So, if someone knows the answer, I'll finally win a discussion :P (and maybe create a new Vim convert<code>:-)</code>)</p>

    1. COAmazing how nobody answering here recognized the need for a proper (partial) parser. Resharper ovbiously implements this (great) feature on top of a logical model of the code: the Code DOM. This is also what enables the refactorings to work on the selections made. Without proper parser you'd select 'things' but not proper (sub)expressions. The latter would be useful, but not currently supported in Vim _That is. unless you count Lisp support: `vabababo2k` is perfect for lisp_ :)

    2. CO@sehe: You are, of course, completely right. I've been thinking about this problem off and on ever since I asked the question here (seems like a long time ago!) and realized that even if I somehow manage to create this feature, it will only work for a specific language, or a family of languages. Too bad, isn't it? :)

    3. COI've been pondering this myself too. I'd be happy with a 90% solution (I can do refactorings pretty swift in Vim manually for now). However a 'usable' subexpression-matching-selection-expander is really my no.1 dream feature. I'm convinced that is is very possible to come up with a parser that will DoTheRightThing for C#, Java, C++ and C; The only sticky edge cases I expect are C# vs. C++0x lambdas. So I'd probably leave those out for a while (and make sure it's pluggable). I'm still deciding what to use, as I kind of loath vim script. I lean towards python, but am weary of excluding userbases

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
