group, and level. Modifiers that affected the translation and
are thus unavailable for application use are returned in
<em class="parameter"><code>consumed_modifiers</code></em>
. See <a class="xref" href="">???</a> for an explanation of
groups and levels. The <em class="parameter"><code>effective_group</code></em>
is the group that was
actually used for the translation; some keys such as Enter are not
affected by the active keyboard group. The <em class="parameter"><code>level</code></em>
is derived from
<em class="parameter"><code>state</code></em>
. For convenience, <a class="link" href="gdk2-Event-Structures.html#GdkEventKey" title="struct GdkEventKey"><span class="type">GdkEventKey</span></a> already contains the translated
keyval, so this function isn't as useful as you might think.</p>

<p>
<em class="parameter"><code>consumed_modifiers</code></em> gives modifiers that should be masked out
from <em class="parameter"><code>state</code></em> when comparing this key press to a hot key. For
instance, on a US keyboard, the <code class="literal">plus</code>
symbol is shifted, so when comparing a key press to a
<code class="literal"><Control>plus</code> accelerator <Shift> should
be masked out.

An older interpretation <em class="parameter"><code>consumed_modifiers</code></em> was that it contained
all modifiers that might affect the translation of the key;
this allowed accelerators to be stored with irrelevant consumed

However, this did not work if multi-modifier combinations were
used in the keymap, since, for instance, <code class="literal"><Control></code>
would be masked out even if only <code class="literal"><Control><Alt></code>
was used in the keymap. To support this usage as well as well as
possible, all <span class="emphasis"><em>single modifier</em></span> combinations
that could affect the key for any combination of modifiers will
be returned in <em class="parameter"><code>consumed_modifiers</code></em>; multi-modifier combinations
are returned only when actually found in <em class="parameter"><code>state</code></em>. When you store
accelerators, you should always store them with consumed modifiers
removed. Store <code class="literal"><Control>plus</code>,

<p>Obtains a list of keycode/group/level combinations that will
generate <em class="parameter"><code>keyval</code></em>
. Groups and levels are two kinds of keyboard mode;
in general, the level determines whether the top or bottom symbol
on a key is used, and the group determines whether the left or
right symbol is used. On US keyboards, the shift key changes the
keyboard level, and there are no groups. A group switch key might
convert a keyboard between Hebrew to English modes, for example.
