<h1 id="page_Swap-Hands-Action">Swap-Hands Action</h1>
|
||
|
<p>The swap-hands action allows support for one-handed typing without requiring a separate layer. Set <code>SWAP_HANDS_ENABLE</code> in the Makefile and define a <code>hand_swap_config</code> entry in your keymap. Now whenever the <code>ACTION_SWAP_HANDS</code> command key is pressed the keyboard is mirrored. For instance, to type "Hello, World" on QWERTY you would type <code>^Ge^s^s^w^c W^wr^sd</code></p>
|
||
|
<h2 id="page_Configuration">Configuration</h2>
|
||
|
<p>The configuration table is a simple 2-dimensional array to map from column/row to new column/row. Example <code>hand_swap_config</code> for Planck:</p>
|
||
|
<pre><code class="language-C">const keypos_t hand_swap_config[MATRIX_ROWS][MATRIX_COLS] = {
|
||
|
{{11, 0}, {10, 0}, {9, 0}, {8, 0}, {7, 0}, {6, 0}, {5, 0}, {4, 0}, {3, 0}, {2, 0}, {1, 0}, {0, 0}},
|
||
|
{{11, 1}, {10, 1}, {9, 1}, {8, 1}, {7, 1}, {6, 1}, {5, 1}, {4, 1}, {3, 1}, {2, 1}, {1, 1}, {0, 1}},
|
||
|
{{11, 2}, {10, 2}, {9, 2}, {8, 2}, {7, 2}, {6, 2}, {5, 2}, {4, 2}, {3, 2}, {2, 2}, {1, 2}, {0, 2}},
|
||
|
{{11, 3}, {10, 3}, {9, 3}, {8, 3}, {7, 3}, {6, 3}, {5, 3}, {4, 3}, {3, 3}, {2, 3}, {1, 3}, {0, 3}},
|
||
|
};
|
||
|
</code></pre>
|
||
|
<p>Note that the array indices are reversed same as the matrix and the values are of type <code>keypos_t</code> which is <code>{col, row}</code> and all values are zero-based. In the example above, <code>hand_swap_config[2][4]</code> (third row, fifth column) would return <code>{7, 2}</code> (third row, eighth column). Yes, this is confusing.</p>
