Try these three things試試這三件事
- Press 1, 2, 3 or 4: edit() swaps the whole line, the circle and the drum card change at once, and the line is listed under it.
- Press Z: undo() goes back one line, as the ↶ on the drum card does. Click a cell or type in the card's line, and rhythmChanged() still tells this page.
- Press S: strudelUrl opens the same rhythm at strudel.cc in a new tab.
- 按 1、2、3 或 4：edit() 換掉整行，圓圈和鼓機卡馬上跟著變，那一行列在旁邊。
- 按 Z：undo() 回到上一行，跟鼓機卡的 ↶ 一樣。點格子或在卡上的那一行打字，rhythmChanged() 一樣會告訴這個頁面。
- 按 S：strudelUrl 用新分頁在 strudel.cc 打開同一段節奏。
Needs: QWERTY keys.需要：電腦鍵盤。
No hardware? Use Drum machine.沒有硬體？用鼓機。
Read these lines讀這幾行
sketch.js:50–51 edit() plays a line as if it were typed on the card and answers { ok, error }.edit() 像在卡上打字一樣換一行，回答 { ok, error }。sketch.js:52–53 undo() goes back one line and says whether there was one.undo() 回上一行，並告訴你有沒有上一行。sketch.js:54–56 strudelUrl is the line as a strudel.cc link; window.open takes it to a new tab.strudelUrl 是這一行在 strudel.cc 的連結，window.open 用新分頁打開。
In the docs文件裡: The cells and the line edit each other格子和那一行互相改
