title: Remove all matching chars in calc sheet with one command
body: <p>My libreoffice calc sheet uses the grave accent character ( ` ) as a prefix to numbers. I want to remove all of these characters in the simplest way possible.</p>
  
  <p><strong>Input sheet:</strong></p>
  
  <pre><code>TABLE    Year1    Year2    Year3
  Price    `0.01    `0.02    `0.03
  Qty      `10      `11      `12
  </code></pre>
  
  <p><strong>Output sheet:</strong></p>
  
  <pre><code>TABLE    Year1    Year2    Year3
  Price    0.01     0.02     0.03
  Qty      10       11       12
  </code></pre>
  
  <p>Currently, I have to use search &amp; replace for each cell to achieve this. I search for ( ` ) and replace all individual instances with a blank. This works, but is very tedious. To make matters worse, Search all and Replace all both result in overwriting the complete cell with a blank instead of just matched character.</p>
  
  <p>How can I solve this issue using the options available in Libreoffice calc?</p>
