but this command is called select enclosing brackets
But the first thing it says is `fixes #2260` so I expected it to do that. Thats not to say that it isn't a useful command in and of itself, but it isn't the answer to #2260.
Where #2260 says:
CTRL-b is a great shortcut, but i cannot select text to matching brace
That is the existing command `goto matching brace`, that is bound to `ctrl_b` by default. Therefore the OP is asking for a version of that to select between the braces. Note that `goto matching brace` does nothing unless a bracket is highlighted, it isn't `goto enclosing brackets`.
So whilst your `select enclosing brackets` command is also a useful one because it works when the cursor is not beside the bracket, its not what was actually asked for in #2260.
As an example, if the cursor is beside a `{` of a C block, which is on a line by itself in the Geany code style, the brace is highlighted irrespective of which side the cursor is on and it seems unexpected to me as a user that the keybinding will select some outer block in the case that the cursor is before the `{` when its highlighted while the goto (ctrl-b) will goto the matching inner brace.
In the best case we should have both functions keybindable as required since they are both useful in different cases.
